1.Propulsion:• means to push
forward or drive an object forward
Latin words: – pro ~forwards – pellere ~ to drive.
The force to propel from a starting point
a machine/engine creates the push an object forward.
2. Suspension:• supports vehicles
weight.
• Makes ride more comfortable!
• Springs, shock absorbers wings, water, & fins
• CONNECTS a vehicle to its wheels.
6 Transportation Subsystems6 Transportation Subsystems3. Guidance systems
• Provide information concerning the control of the vehicle.
• Guidance systems can be simple or quite complex.
• Maps, GPS, traffic lights, keels, computers
4. Control systems
•Control speed and direction of a vehicle’s path.
•Steering & brakes, rudders & flaps, propellant (rockets)
6 Transportation Subsystems6 Transportation SubsystemsSupport systems
• Used to maintain vehicles.
• Services and keeps everything working
• Garage, gas stations, mechanics, control tower, marinas, NASA
Structural systems
•the basic framework of the vehicle.
•accommodate a vehicle’s cargo and form
• a.k.a.: chassis, body, hull or fuselage
