CURITY CLASSIFICATION OF THIS PAOG(Vhu, Data Rgio red)

An AN/PVS-5 simulator has been designed at USAARL to supplement night visiongoggle (NVG) training for ground units. This report discusses the specifi:a-tions, characteristics, applications, benefits, and costs of the AN/PVS-5simulator prototype.

The AN/PVS-5 simulator is a low-cost item consisting of the standard faceplate(without eldotrical components) and cushion with a sheet metal atid filter in-sert that does not use batteries, which are the highest life cycle costs for NVGoperations. The NVG is simple and easy to use, and durable with little or nomaintenance requirements. It is designed for daytime training - indoors or out-side as long as the ambient light is at a photopic level. The device effective-ly simulates most NVG conditions to include a 40 degree field-of-view, reducedacuity, loss of peripheral vision, loss of color cues, added out-of-balanceweight, closed-in feeling around the face, etc.. The AN/PVS-5 simulator isemployakle in most operational and environmental ituations and is at least assafe to train with as actual NVGs. 1Fielding an NVG training simulator would reduce ear and tear, and increase thelongevity of actual NVGs. Supplementing training with the simulator would offersubstantial cost savings by reducing the consu tion of batteries used to powerthe actual NVGs. The NVG simulator has additi nal pragmatic advantages overactual NVGs by its durability und widespread #ission or training applications.The AN/PVS-5 simulator would supplement trai ing equipment needs for units re-ceiving fewer NVGs than their basis of issue/due to procurement and budgetaryrestrictions.

Concept

To provide a low-cost, low-maintenance, realistic stmulatorto be used in training with the standard AN/PVS-5 cight.Visiongoggles (NVG).

Statement of need

AirLand Battle doctrine places an emphasis on night trainingfor all combat and combat support units. Future combatoperations will stress exploiting all tactical environments, 24hours a day. This will lead to an increased emphasis on nighttraining with night vision devices Armywide.

While night vision devices such as night vision goggles(NVG) have been fielded in the Army for years, only the aviationcomponent has well-established, specific qualification andcurrency requirements for NVG training and operations. Asidefiom aviation, NVGs have been authorized for infantry, armor,military police, logisticians, medics, maintenance, and many

other ground units and personnel. Some ground units such as the9th Infantry Division and many units in Europe already have been

training with NVGs for an extended period. However, manyauthorized units do not have enough NVGs with which to train.Some units that have NVGs are reluctant to train with them for'fear of loss or damage, are unfamiliar with their use, and avoidtraining in the absence of established skill qualificatioatraining (SQT) requirements or an Army Test and EvaluationProgram (ARTEP). Currently, this is being remedied by revisionsin unit TOEs, continued NVG procurement, and the writing andestablishment of guidelines, SQT requirements, and ARTEPs for allunits as they gain NVG capability.

Unfortunately, as the requirement for NVG training andcapability increases Armywide, the costs Increase. These coutsinclude initial procurement, maintenance, battery supply, repair,and replacement. For ongoing training, the cost of batteriesalone, necessary to power the NVGs, is substantial. In fact, thedriving cost factor in the life cycle of NVGs is batteries. Tohelp defray life cycle costs, the Army could benefit greatly byevploying a realistic simulator to s,,pplement NVG training.

An NVG simulator should have most or all of the followingproperties:

1. Low cost.2. Durable with little or no maintenance requirements.3. Simple and easy to operate.

3

4. Effective simulation of most NVG features (for example:field-of-view, added out-of-balance weight, reducedactiity, loss of peripheral vision, loss of colorcues, closed-in feeling around the face, etc.).

5. Employable in most operational and environmentalsituations.

6. At least as safe to train with as actual NVGs,7. Well-suited for training during daylight duty hours*8. Usable in qualification training or in meeting train-

ing requirements.

9. Similar parts (if employed) could be available as sparesfor actual NVGs.

The following description is a concept proposal for anAN/PVS-5 simulator that meets all nine of the listed criteria foreffective simulation of the daylight training NVG environment.

Description of simulator

A draft drawing and a series of photographs of the prototypeare shown at the end of this report. The proposed NVG simulatorconsists of an insert which is placed inside a standard AN/PVS-5faceplate. The insert is made of 22-gauge sheet metal,constructed from three pieces, joined by soldering or spot welds.Each viewing port is punched o~t and drum sanded. A soft plastichose is split and glued to the septum with epoxy to protect thenose from the edge of the sheet metal.

Constructed to the general dimensions given in Figure 1, theinsert fits snugly into the standard AN/PVS-5 faceplate withoutlight leaks or glare problems. Painting the insert a flat blackfurther reduces the glare during daytime viewing. Since theinsert is snugly fit, it still can slide in and out, allowingadjustment of the septum close enough to the nose to preventviewing from either eye through the opposite hole of the insert.

The septum and lambskin face cushion can be modified toallow a soldier to wear spectacles when using the simulator. Asimple modification to only the face cushion as shown in Figure10 allows a soldier to wear spectacles with the aviator-styleframes (Bayonet Temple, NSN 6590-01-099-2321). With additionalmodification of the faceplate, cushion, and insert as shown inFigures 11-13, the standard black, plastic spectacles (S-10Eyeshape, NSN 6540-00-482-0000 [remaining four-digit numberrefers to sizes J) can be worn when using the simulatort Eventhe new brown frame spectacle (6540-01-147-4670) is suitable,

4

The length of the insert is designed specifically to reachthe lambskin face cushion on the inside of the goggles as the lipon the front of the insert abuts the front of the faceplate.This puts all of the pressure against the faceplate cushion incase of accidental impact while the simulator is worn.

The front of the insert is made at a slight angle so viewingthrough the insert appears more comfortable; that is, aboutperpendicular to the normal optical axis. As long as the wearerhas an average-sized nose and interpupillary distance (from 60-68mm), adjusting the insert as close as possible to the face willyield either an individual eye or combined stereoscopicfield-of-view comparable to NVG viewing, or about 40 degrees.The farther the viewing ports from the insert, the smaller thefield-of-view. Conversely, shortening the insert could yield awider field-of-view. Thus, one size will work for all users.

The weight of the prototype insert is 9.7 ounces; thesLripped down faceplate without the electrical components weighs4.3 ounces for a total of 14 ounces. This is less than thestandard AN/PVS-5 (1.9 pounds), but thin lead or heavy metalstrips could be attached securely inside the lateral sides of theinsert or on top of the faceplate to equal the actual NVG weight.

To better simulate NVG viewing, a green color filter made ofpolycarbonate is attached to the outside of the viewing portplate. The filter material used in the prototype is a 3-mmthick, blue-green polycarbonate filter with a peak transmittancebetween 470 nm and 550 nm. This filter passes a dominantwavelength approximately equal to the phosphor amittance ofactual NVGs.

While the blue-green filter allows nearly 20/20 acuity, thiscan be reduced to NVG-comparable acuity (about 20/50) by adding asheer mesh screen such as a woman's nylon stocking. In fact,gceen ultLaaheer nylon stockings were used in the prototypes.The blue-green color filter and green nylon stocking work well insimulating the actual NVG phosphorescent image for its color,acuity, stippled image, and loss of color cues.

The nylon stocking in the prototypes is sandwiched between a1.8 mm clear plexiglass shield and the 3 mm blue-green filter.The filter system is bolted to the front of the simulator insert,rough sanded around the edges, and sealed with a silicone epoxyto further protect the nylon mesh screen.

During daytime use there is a small region of vililltydown around the nose when the simulator is worn. Most of thiscan be eliminated by a small flap of duct tape or leather

material being attached along the bottom inside curvature of thestandard faceplate. However, our experience with the simulatorhas convinced us that this is not necessary because the area iswell below the normal field-of-view. Figure 14 shows a prototypewith a leather flap attached to the bottom of the faceplate toprevent light interference,

Cost

Approximate costs to produce the simulator prototypes aregiven in the following cost summary. Cou:t figures are based onthe average cost per unit for 22 production prototypes. For easycomparison, a cost summary for the AN/PVS-5 also is given here*

AN/PVS-5 simulator (prototypeal

Faceplate without electrical components $ 10.00Lambskin face cushion (GSA price) 21.53Polycarbonate blue-green filters 50.00Fabrication of insert 50.00

Approximate cost per prototype: $ 132

For a larger order, industry cources indicated thatpolycarbonate filters would cost well below $50 each. In massproduction, the NVG simulator should cost less than the cost ofproducing each prototype. There is no reaoon the insert couldnot be produced out of a hard, durable plastic or polycarbonate.The removable blue-green color filter easily could be produced orprocured with the proper dominant wavelength, luminoustransmittance, and opacity to yield equivalent NVGcharacteristics. Compared to the cost of an actual AN/PVS-5, thesimulator is a genuine bargain.

Usefulnes as. a learning aid

The proposed NVG simulator especially would be useful ininitial qualification training as a close approximation to anactual night vision goggle, but also would be a useful adjunctfor SQTO ARTEP, or premission daytime training because of theeffective simulation of actual NVGs that it offers. Fivedifferent adjustments have to be accomplished for a soldier tobecome and remain proficient in NVG operations.

1. The soldier must adapt to the limited, 40 degreefield-of-view and loss of peripheral vision. This furtherrequires developing better scanning techniques by making morehead and body movements, but not too rapidly.

2. The soldier must get used to the closed anduncomfortable feeling experienced when having the NVG faceplatepressing against the face.

3. The soldier must become adapted to the added,out-of-balance weight inherent in NVG operations, sometimes forextended periods of time (2 hours or more).

4. It also is well established that NVG operations ore .achmore stressful and fatiguing than most other operationalenvironments (FC 90-1). Even with a lot of training andexperience, NVG operations still cause significant stress andfatigue. Adjustment to these factors only can be made withexperience in NVG operations.

5. Finally, a soldier must become well acquainted with NVGsas an optical device. This involves learning to make diopter andfocal length adjustments, setting interpupillary distance, andinterpreting phosphorescent images of limited acuity compared tonormal, accommodated vision, without the benefit of color vision.

The advantages of this simulator are simplicity of design,durability, low cost, and effective simulation of mostlearning/adaptation parameters inherent in NVG operations. Theproposed NVG simulator would be useful in simulating thefollowing adjustment parameters:

1. The device has a comparable field-of-view, eliminatesperipheral vision, and requires similar scanning techniquou whencompared to the standard AN/PVS-5 NVG.

7

2. Since the same faceplate is used in the simulator andAN/PVS-5 NVCs, adapting to the closed-in feeling and pressureagainst the face would be identical.

3. Since the simulator could be made to weigh as much asthe standard AN/PVS-5 NVG, adjusting to the out-of-balancecondition and added weight to the head also would be identicbl.

4. The NVO simulator offers several advantages to trainingover the exclusive use of NVGs in night operationt. Use of theNVG simulator in the daytime environment would be less stressfuland fatiguing than the use of AN/PVS-5 NVGs in actual nightoperations primarily because there would be no disturbance of asoAdier's normal, light-dark biological cycle. By "successiveapproximations," an istablished, effective learning technique,soldiers will transition more easily and safely into NVGoperations. Experience and familiarity with the simulator alsowould help reduce some of the stress and fatigue that occurs whdsactual NVG training is conducted.

5. The system does not contain any electro-opticalcomponents such as lenses, a photomultiplier, or phosphorescentscreen. Were it to do so, however, the system would cost a lotmore money, thereby nullifying one of its principal advantages.

Training and Lurrency applications

The NVG simulator is best suited for a daytime trainingenvironment--indoors or outside as long as the ambient light isat a photopic level. Although not recommended, the device cculdbe used at night for unaided conditions, but the blue-greenfilter and mesh screen would have to be removed,

Currently, NVGs have been authorized for all combat units,and most combat support and combat service support units.Aviacors currently use a modified AN/PVS-5 NVG that allowslook-under capability and some peripheral vision. The modifiedAN/PVS-5 will be used by aviators until replaced by the AN/AVS-6(ANVIS). Unfortunately, the NVG simulator is not suitable as atraining aid for the aviator using the modifiedA-AN/PVS-5 orANVIS; however, other aircrew members will continue to use theAN/PVS-5 with the full faceplate.

Presently, some 36,000 NVGs are in use by the Army, with71,000 more anticipated to be in the field by the second quarterFY 87. But, that number still falls far short of the numberneeded to train all the troops authorized and expected to becomequalified in NVG operations. The requested basis of issue is for

8

140,000 NVGs. TOE units with limited numbers of NVGs especiallycould benefit from this NVG sLmulator to help meet trainingrequirements.

We recommend having a specified number of days and timesthat trainees would be required to wear the simulator. forqualification training, a soldier could be required to wear thesimulator for up to 5 training days, starting at 2 hours andincreasing to 4 hours each day. For currency, a qualifiedsoldier could be required to use the simulator during routinetraining for at least 10 hours every 6 months at no less than 2hours per wearing. Using the NVG simulator wuuld not necessazilyadd additional time to any current training syllabus.

A soldier can perform safely almost any type of job ortraining activity while wearing the NVG simulator, be it drivinga truck or low-crawling under barbed wire. In fact, because ofthe device's durability, it could be used in any weathercoiditions or in a dust-filled environment where commanders maybe very reluctant to conduct training with the actual NVGs.

A daylight training simulator would be useful especially infar northern latitudes when there are long seasons with little orno dark periods. The simulator also would be a practicalsolution to units with limited or restricted opportunities orfacilities for actual night training, e , National Guard andReserve units. Finally, there would be additional cost savingsby being able to supplement training during normal duty hourswhen night facilities, ranges, and extra required personnel wouldbe more costly.

The AN/PVS-5 is anticiated to remain in the inventory untilat least 1995. This would make the NVG simulator useful foryears to come. However, even with the addition of other genericNVGs and possibly a single objective tube AN/PVS-7 NVG, this NVGsimulator would be useful for these models as well. Even theAN/PVS-7 with a single objective tube still will have two viewingtubes with about 40 degree fields-of-view.

Logistical considerations

Fortunately, there would be little or no maintenance toworry about with the NVG simulator. The same supply personnelwho issue and maintain NVGs would handle the simulators. Thefaceplate with the electrical components requires no configuralchanges to accommodate the training insert, leaving it readilyavaila" .u as a spare part when needed for the standard AN/PVS-5model.

9

Advantages and benefits

Currently, there is no such training aid in the Army orelsewhere. The tangible advantages and benefits of adopting theproposed simulator are:

I. 'Transition into NVG operations would be simplerand safer.

2. Supplementing training requirements by replacingthe expensive NVG in certain training environmentiwould reduce wear and tear, thereby increasing thelongevity of actual NVGs.

3. Supplementing training with the NVG simulator wouldoffer additional cost savings by substantiallyreducing the consumption of batteries used to powerthe actual NVGs.

4. It would provide additional pragmatic advantages overNVGs by its durability and widespread missionapplications. As now configured, only NBC groundmissions and aviation missions would be excluded,

5. It has all-weather and all-terrain capabilities.6. The AN/PVS-5 simulator would supplement training

equipment needs for units receiving fewer NVGs thantheir basis of issue due to procurement andbudgetary restrictions.

Daylight filters and NVGS

Without getting into too much detail, training with thissimulator in the daytime environment would be far superior tousing actual NVGs with any type of daylight filters. Drawbacksto daylight filter use are possible tube damage from daylightexposure, lens fogging, reverse imaging of bright objectsp andgreatly reduced contrast and resolution. Currently, sharedapertures (lens covers with a small hole in the center) are notauthorized for daytime training for the reasons alreadymentioned, and because daytime use more rapidly degrades theimage intensification capability of the system.

Army aviation uses special purpose filters for daylight NVGtraining, but only 3,900 sets were purchased at $257 per set.These filters have all the drawbacks already described, addsignificant weight to the front of the NVGs, and cost much morethan would the NVG simulator. It's unfortunate that the AN/PVS-5simulator as configured in this proposal does not satisfy therequirement for aviator NVGs to have a look-under capability, tsdoes the modified faceplate AN/PVS-5 and ANVIS.
