Abstract: In wheel type of landing gear helicopters landing gear wheels and tyres are used for ground maneuvering. So for smooth ground maneuvering; run on take off; run on landing and for helicopter spot turning a brake system is mandatory for wheel type landing gear helicopters. The objective of this paper is to give a simple; basic and generalized design procedure to design a wheel brake system of a wheel type landing gear helicopters; the design should meet INDUSTRY standard requirements and analyzing the kinematic behavior of wheel brake pedal system using ADAMS software. The pedal system is modeled in ADAMS software by using joints of the pedal system as definition points and individual part characteristics. After simulating the model for 20 degrees of pedal travel the characteristics of Brake Master Cylinder axial load and Pedal torque data are acquired from ADAMS postprocessor.
