The nose wheel tricycle landing gear has been the preferred configuration for UAV. The most attractive feature of this type of undercarriages is the improved stability during braking and ground maneuvers. The results of present study indicated that landing gear stability could be improved by longer wheel axle stiffer damping mechanism and smaller wheel mass and lower aircraft sinking velocity. The present approach has been following the recommendations of the previous design of landing gear layout of other aircraft and international standard federal aviation regulations FAR . More work to be done to prove the viability of this conceptual layout design. Detailed results needed further simulation study for validations.

Unmanned aerial vehicle An unmanned aerial vehicle UAV commonly referred to is a remotely piloted aircraft. UAVs come in two class some are controlled from a remote location and others fly autonomously based on pre-programmed flight. There is a wide variety of UAV shapes sizes configurations and characteristics. UAVs perform a wide variety of functions. The majority of these functions are some form of remote .
