Top best answers to the question «Why was the electric propulsion system so important»

  • This electric propulsion system, the scientists believed, could develop sufficient thrust in frictionless space to propel large spacecraft over vast distances. "The small thrust (from the electric propulsion system) is effective for missions to the more distant parts of the solar system," von Braun wrote in the 1950s.

FAQ

Those who are looking for an answer to the question «Why was the electric propulsion system so important?» often ask the following questions:

👉 What is electric propulsion system?

Electric Propulsion (EP) is a class of space propulsion which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means.

👉 How does a hybrid electric propulsion system work?

  • For all-electric configurations noise and vibration are improved by elimination of the main reduction gear For hybrid electric drive architectures requiring a shaft-mounted motor Leonardo DRS offers power-dense, low speed PM motors with a large air gap that allow for a bearing-less configuration, simplifying the propulsion shaft.

👉 How electric motors can power a propulsion system?

  • Hybrid electric: A combination of batteries and combustion engines provide propulsive power. In parallel hybrid designs, a battery-powered motor and a turbine engine are both mounted on a shaft that drives a fan, so that either or both can provide propulsion. In series hybrid designs, only the electric motors are mechanically connected to the fans; the gas turbine drives an electrical generator, which produces power to drive the motors and/or charge batteries.

How electric motors can power a propulsion system in two?

The control strategy for the power distribution of energy between the motors is a decisive factor in the minimization of power losses of the propulsion system. In the work of Zhang and coworkers [ 8 ], the dual motor coupling propulsion system (DMCPS) is presented. The DMCPS can work with one or two electric motors.

How to choose an electric propulsion system for your boat ?

This is to say : The autonomy is dependant from the power consumed by your electric motor and the capacity of your battery. The calculation is : Power of the battery / used power. In this way, for an electric motor from 55 lbs and using 70 ampere (on maximum speed) supplied by a 80 Ah (lithium battery), we will get a 1 hour and 9 minute autonomy (80/70=1.15)

What is diesel electric propulsion?

Diesel-electric propulsion. Electric propulsion with diesels used as prime movers. Diesel-electric drive takes less space than the equivalent direct-drive two-stroke engine allowing the aft section to be slimmer and giving better flow over the propeller. Not only is the diesel-electric drive train lighter than a two-stroke engine, but also its ...
