Uçan Arabaların İniş Takımı ve Süspansiyon Sisteminin, İniş ve Engel Geçme Manevraları için Performans Modellemesi

Abstract

Recent research and development activities in both in aviation and automotive industries resulted with a genuine product known as roadable aircraft also known as flying car. Roadable aircraft is combination of a small size airplane and a passenger vehicle containing the superior sides of both products; and provides door-to-door transportation by both ground and air. Many companies invested in this product and first commercial units are expected to be the launched within 5 years. Suspension system of a roadable aircrafts plays a significant role in the overall product design, as it should satisfy the customer requirements for both aircrafts and passenger cars: landing and traveling on road. In this study, suspension system of a flying car was modelled in Matlab/Simulink and optimized as a quarter car model employing a 2 DOF Mass-Spring-Damper system. The equations of motion were presented, and the model was firstly simulated as an aircraft landing gear for landing performance. Then the model was run to determine driving performance on road for a typical bump passing manoeuvre. A set of design parameters was determined for acceptable performance outputs: suspension system damping element acting force and displacement for the landing and maximum acceleration for the bump passing performance.
