Project-1: Powertrain for aircraft in runways Part A: Search and list out the total weight of various types of aircrafts.  Ans. Classification of aircrafts are as below: According to the purpose, principle, types of wings, material and components used, the size and weight of the aircraft varies as mentioned in above…

WEEK 11 CHALLENGE For a defined driving cycle, calculate the energy required for braking. Ans.   There are two kinetic types of energy that are involved in a moving car: Linear and rotational kinetic energy, Ke linear=1/2 *Mv2 ; Ke rotatinal=1/2*Iω2 The deceleration from V1 to V2 will reduce the…

WEEK:7 CHALLENGE 1. a) Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. b)Comment on the armature current shoot-up from the scope results. c)Refer to the help section of ‘The Four-Quadrant Chopper DC Drive (DC7) block’. Compare it with the H-bridge model. Ans.…

Which types of power converter circuits are employed in electric and hybrid electric vehicle?  Ans. The figure below shows how Power Electronic Converter is used in different configurations of vehicles. Few of the power electronic converters used in EV/HEV vehicles include: 1.DC/DC Converters used for supplying Low…

WEEK 4:   1.What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type? Ans. Mapped Model: Mapped model uses pre-defined value sets.It is generally used for quasi-steady state analysis. Mapped model is used when there is no need of detailed component level…

CHALLENGE 3: For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations. Ans: For one duty cycle, the vehicle can travel upto 17.8 Km and the battery doesn’t discharge completely. For two duty cycles, the vehicle…
