Project-1: Powertrain for aircraft in runways
2. Is there any difference between ground speed and airspeed? Answer:- 1. The aircraft usually operates inland as well as in air and so we need to study their speed difference in-ground and in air 2. The ground speed and the airspeed usually change based on the wind component. 3.If we consider that there is…

Final Project: Electric Rickshaw modelling
Power Controller: This subsytem is of prime importamce in electric powertrains. The controller does the main work of limiting and providing the required voltage. The system uses an HBridge block, controlled PWM voltage block, two controlled voltage source blocks for acceleration and deceleration(braking). This is because…
