Simulation, Fabrication and Testing of UAV Composite Landing Gear

Simulation of the Dynamic Behavior of Aircraft landing Gear Systems

Simulation and the resulting prediction of the dynamic behavior of an aircraft and its landing gear system during ground maneuvers is an essential part in the design process. A realistic estimation of unwanted oscillations, such as gear walk and shimmy, for the landing gear and whole aircraft can be readily obtained with an MBS-model. It is then possible to adjust the model for changes in the s...

Electrically Driven And Controlled Landing Gear For UAV Up To 100kg Of Take Off Mass

UAV Unmanned Aerial Vehicle is very rapidly growing area of flying objects. Various tasks and possible areas of UAVs use are generating increasing demand for various types and designs. Thanks to simpler certification requirements UAV market could be used as a test field for various new technologies like wide use of modern electric systems. One of the area where electric systems could be impleme...

Unsteady Simulation of a Landing-Gear Flow Field

This paper presents results of an unsteady Reynolds-averaged Navier-Stokes simulation of a landing-gear flow field. The geometry of the four-wheel landing-gear assembly consists of several of the fine details including the oleo-strut, two diagonal struts, a door, yokes/pin and a flat-plate simulating the wing surface. The computational results, obtained by using 13.3 million grid points, are pr...

Aircraft Landing Gear Design & Development

Landing gear is one of the critical subsystems of an aircraft. The need to design landing gear with minimum weight, minimum volume, high performance, improved life, and reduced life cycle cost have posed many challenges to landing gear designers and practitioners. Further, it is essential to reduce the landing gear design and development cycle time while meeting all the regulatory and safety re...
