Week-6 Challenge: EV Drivetrain

Aim :  Powertrain for Aircraft in runways. Introduction: Aircrafts does not always work on engines when they are on ground, because engine power for the airplanes can be hazardous on the ground. so when they are moving on the ground are usually with towing with vehicle. But heavy airplanes with carrying capacity more…
