Solution: 1. Aircraft Gross Weight:   The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at any moment during the flight or ground operation. An aircraft's gross weight will decrease during a flight due to fuel and oil consumption. An aircraft's…

  1st ANSWER                                     Electric Motor Braking :     Eectric motor can’t develop braking torque at high speed similar to starting, because Braking torque is applied in the opposite…

      The Bipolar Junction Transistor (BJT) when used for power switching applications, operates as an IGBT. When it is conducting (BJT operating in the saturated region), a forward voltage Vf is developed between collector and emitter (in the range of 1 V). Therefore, the IGBT block can be used to model…

Q1) Which types of power converter circuits are employed in electric and hybrid electric vehicle?      ANS:   There are 4 main categories of power converter circuits which are used in electric and hybrid electric vehicles. They are listed and elaborated upon below:   AC to DC converter This…

  1st Answer   Mapped   Model uses a set of steady-state lookup tables to characterize engine performance. The tables provide overall engine characteristics, including actual torque, fuel flow rate, BSFC, and engine-out exhaust emissions. If you have engine data from a dynamometer or a design tool like GT-POWER.…

1st Answer for the vehicle with the same default configuration cannot pass the mark of 45kmph and it has exhausted its energy at 41.5kmph  with all the parameters kept unchanged, the vehicle simulation is done         2nd Answer now by changing the battery parameters it can be concluded that the…

MATHEMATICAL MODELING OF  DC MOTOR A DC motor is an electrical machine that converts electrical energy into mechanical energy. In a DC motor, the input electrical energy is the direct current which is transformed into mechanical rotation.     DC motor consists of a stator and rotor, the stator of the…
