24 gru 2022 · 1- Drag coefficient for a retractable landing gear. I tried the following equations: CD,gear = WingLoading * FlapDeflection * (( AircraftMass(TO,LD))^-0.215) CD0,gear = SUM i=1 > n [CD,gear(AreaLG / WingArea)] The results were ASTRONOMICAL. 2- Weight of main and nose landing gears.
Landing gear design is ruled by a set or requirements. Some of them are common for all transport aircraft as the they are defined in the airworthiness requirements of FAA and EASA.
17 maj 2022 · The landing gear, or undercarriage, has two primary requirements: (1) to support the aircraft while on the ground and (2) to absorb the large loads associated with landing, and transfer these from the wheels to the aircraft’s primary structure.
A landing gear, also known as an undercarriage, is a complex system of different components that are used by an aircraft for the purpose of takeoff and landing. A typical landing gear consists of various structural members, hydraulics, brakes, wheels, tires, energy absorption components, etc.
7 lip 2015 · There are lots of forces acting on the gear at the point of landing. The best way to minimize loads on the gear is to land smooth (I know that sounds obvious). For what it's worth you do not necessarily want to spin up the gear before landing for a few reasons.
1 paź 2020 · The paper presents a preliminary calculation method, which is easy to apply for pre-dimensioning the landing gear. Preliminary calculation of the landing gear includes estimating the...
Determining the main features of the geometric characteristics of a landing gear is an iterative process conditioned by regulatory provisions, by the values of the reactions in the wheels of the gear, by the stability conditions and by the the propeller ground clearence
