The “Electro-mechanical Landing gear system Integration for Small Aircraft” (E-LISA) research project has the objective of developing an innovative “iron bird”, a testing facility dedicated to executing tests on landing small aircraft. This document presents structural analyses this complex machine performed with Finite Element Method (FEM). Key purposes these numerical simulations were quantif...

A case study problem based on a set of aircraft landing gear is examined in Hybrid Event-B (an extension of Event-B that includes provision for continuously varying behaviour as well as the usual discrete changes of state). Although tool support for Hybrid Event-B is currently lacking, the complexity of the case study provides a valuable challenge for the expressivity and modelling capabilities...

Dynamic behaviour of motorcycles front wheel are not different to similar wheel suspensionmotion of airplanes and road vehicles. In every case self excited oscillations caused bythe tire occur. Only the different design of wheel suspension produces some differentcoupling. The deviation of a moving wheel on a horizontal plane from straight rolling iscaused by unstable lateral con...

Thedevelopment of Unmanned Air Vehicles (UAVs) for both military and civilian applicationslead the opportunites for the development of advanced technologies to improve their operational performance. Due to various mission requirements UAVs will carry different types of payloads which change the total all-up weight. The landing gears of the UAVs should be optimized to the changing weights and va...
