Wheeled Landing Gears


Wolfram

Recommended Posts

I think the title itself explains a lot but the idea is having a second type of Landing Gear elements that have wheels and are more geared towards gravity landing and takeoff.

 

Their main use would be to keep the ship at some height from the ground while still moving forward but without enough lift to keep it flying, which would be useful when taking off or landing with large amounts of cargo, and would require a landing strip to properly land, similar to real planes.

 

In terms of implementation, the retractable part of it could be borrowed from existing landing gears and the physics part could be similar to these of a hover engine, the wheels would not provide any thrust, just maybe a very small braking force, but mainly sustentation/suspension for the ship when they are in contact with the ground, so the ship would still need to brake by itself.

Btw, aircraft's landing gear in real-life is called an "oleo strut". "Oleo" means it is pneumatic (it uses air). So what you have is something like an actuator (an outer cylinder and a piston called an inner cylinder that fits inside it. both are held together by the scissor-link). The cylinder is divided by the orifice into 2 sections: upper chamber which is serviced with nitrogen (because it is the least corrosive) and lower chamber which is serviced with petroleum-based hydraulic fluid called mil-h-5606 which is the standard (when you have to lube that piston, you must use 5606 as well, nothing else). This is what they use to cushion the impact of landing (pressurized air, not a spring coil like in a car). A spring coil bounces, dampening the air slowly from the compression of the actuator from landing does not cause bouncing and it absorbs the energy of landing.
