DESIGN & ANALYSIS OF A HELICOPTER LANDING GEAR
From the assignment brief
You will be provided with some typical data ranges for this type of helicopter, including the mass and some of the dimensions. You will need to find any additional figures you need by research or calculations. The design criteria is deliberately open, it is up to you how many wheels you use and how you model the system in Adams/view. Simulations should be validated with hand calculations where possible.
Data relating to naval helicopters
The ranges given are a guide – if your research uncovers something outside these ranges, it is ok to use it, just make it clear where the information has come from.
Length of helicopter body (not including rotor blades) – 12.5 to 20 meters
Width of helicopter body (not including rotor blades) – 1.5 to 3.2 meters
Empty mass – 2500 to 11,000 kg
Fully loaded mass – 4500 to 15,000 kg
Ground clearance – typical ground clearances vary based on the landing gear used, you need to research this in order to justify your design for the landing gear arrangement. Your mechanism should simply be a sensible size, it does not have to perfectly mimic an existing system.
Steering– you do not need to concern yourself with the steering mechanism, which allow the craft to be manoeuvred on deck.
Retraction – you do not need to concern yourself with the retraction mechanism, which pulls the landing gear into the body of the craft when in flight.
