Question

The main landing gear of a transport aircraft exerts a maximum force by the retraction actuator is 12000 lb and the actuator stroke is 14.25 in. Assume following: The gear must be fully retracted in 10 second. There are two main gear unit and a nose gear which are identical 3) Maximum system pressure is 3000 psi. The required actuator size, that is, cylinder bore and piston rod diameters. Use a 2:1 area ratio for the rod and head end areas. What does this ratio imply for the performance of landing gear. Calculate the hydraulic power (in Horse power) to retract all three landing gear units simultaneously.

Answer 1

Answer:

The main landing gear of a transport aircraft exerts a maximum force by the retraction actuator is 12000 lb and the actuator stroke is 14.25 in. Assume following: The gear must be fully retracted in 10 second. There are two main gear unit and a nose gear which are identical 3) Maximum system pressure is 3000 psi.

The required actuator size, that is, cylinder bore and piston rod diameters. Use a 2:1 area ratio for the rod and head end areas. What does this ratio imply for the performance of landing gear.

Calculate the hydraulic power (in Horse power) to retract all three landing gear units simultaneously.
