Abstract
In general aviation, pilots use either a tow bar or a tug to maneuver their planes to and from its parking place. A tow bar is a lightweight human powered device that allows a pilot to push and pull his/her pane by themselves using human power. A tug is a similar device, except much bigger and heavier, and is electrically powered, allowing for an easier time maneuvering a plane. The downside to a tug is since they are bigger and heaver, they cannot be taken with a pilot on a trip. The goal of this project was to combine the best parts of both devices, making something that is electrically powered and able to maneuver a Cessna 175 on its own, but is small and light weight enough to be taken with on a trip. The device is made from a 20:1 worm gear set, powered by a 20V DeWalt cordless drill. The drill power is transferred through the gearbox to a set of 8-in pneumatic wheel that will push and pull the aircraft. All these parts are connected to a frame made of 1”x1” T Slot extrusions. The frame can be taken apart into smaller pieces to allow for storage inside a Cessna 175. This project was tested on three areas; ability of device, weight, and storage. The device was successfully able to maneuver a plane on its own, as well as able to be stored in a Cessna 175. Unfortunately, the device’s weight is 20 percent over target.
