MATLAB Assignment
Design the retraction and extension mechanism of the main landing gear for an aircraft, which is attached to the fuselage and retracts to the fuselage. When the body landing gear is in the extended position the landing gear is 31.7 inches below the fuselage. The length of the landing gear with the tires is 191.2 inches. The landing gear is stored a compartment that is 16.96 ft long and 8.3 ft high. The landing gear should fully extend within 20 second.
Perform the following:
Linkage synthesis
position analysis
Velocity analysis
Acceleration analysis
Where should you place the driving actuator to extend and retract the body landing gear of the aircraft?
How fast should the actuator move?
