Aeronautical & Aerospace Engineering : Spaceflight Mechanics - Quiz(MCQ)
For military operations requiring high energy, which of the orbits is used?
A)
Hohmann transfer
B)
High energy orbit
C)
Electric propulsion transfer
D)
Low-thrust chemical transfer

Correct Answer :   High energy orbit


Explanation : For military operation mission, more energy is required than what is required for the Hohmann transfer. High energy orbit is used when transfer time is of the essence. In this operation, an impulse is given at the initial circular orbit which pushes the spacecraft into an elliptical orbit. After reaching the desired point, another small impulse is given to circularize the orbit and place the spacecraft at the desired altitude.
