  • 1. AIM INTRODUCTION Drag and mach number Comparison Variant of Design features CONCLUSION

2. Aim of this presentation is give brief idea aboutswept wing configuration and its applications on super sonic flight 3. A wing planform favoured for high subsonicjet speeds.To reduce the wave drag.first investigated in Germany from 1935onwards.introduction of the MiG-15 and NorthAmerican F-86 . 4. When aircraft enters the transonic speedsjust below the speed of sound, an effectknown as wave drag starts.Near the speed of sound oblique shockwave is generated. Shock waves require energy to form. 5. which characterizes a swept wing isconventionally measured along the25% chord line. 6. forward sweep 7. Allowing more space in generally crampedcorporate jet cabins Relatively expensive. Highly maneuverable at transonic speeds 8. Extra lateral stability. Longitudinally stable on its own. Delay the compressibility effect when flyingat transonic speed. 9. Also known as swing wing. That may be swept back and then returned toits original position during flight. 10. Aeroelastically enhanced maneuverability Smaller basic lift distribution Increased trailing edge sweep for given structuralsweep - lower CDc Unobstructed cabin Easy gear placement Good for turboprop placement 11. Aeroelastic divergence or penalty to avoid it Lower Cn (yaw stability) Bad for winglets Stall location (more difficult) Reduced pitch stability due to additional lift andfuse interference
