Part A: 1. Search and list out the total weight of various types of aircrafts.  ANS:       An aircraft is a vehicle or machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases…

QUESTION 1: 1.What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Ans:powertrain blockset provides two types of combustion engine models:mapped and dynamic. Mapped engine: 1.Mapped engines represent macro engine behaviour as a set of lookup tables(brake…

Electric Vehicle: An electric vehicle runs on pure electricity without any consumption of conventional fuels. Any automobile that is propelled by an electric motor, using energy stored in the battery is called a pure electric vehicle. Battery electric vehicles store electricity on board with high-capacity battery packs.…
