MAE146: Astronautics – Homework Assigned: Wednesday, February 24 th , 2010 Due date: Friday , February 26 th , 2010, (at the beginning of the lecture) Please justify all of your answers. Write your answer cleanly with sentences and diagrams to explain. Don’t forget to write your name on your copy to receive credit. Problem 1 (5pts): On the notion of Δ V Solve problem 6.26, page 383-384 of textbook (current edition). The problem consists of computing the total Δ V given velocities of 3 orbits at the intersection points. Problem 2 (10pts): On plane change Solve problem 6.38, page 388 of textbook (current edition). The problem consists of computing the value of plane change Δ i given the position and and Δ V vectors. Problem 3 (15pts): On apsidal change

The problem is about Further study: Further reading on plane changes with simultaneous change in eccentricity would be useful and illustrate the one-impulse transfer cases further. Optional problem 1 (on escape speed): Given an elliptical orbit of eccentricity e and semi-major axis a , compute the minimum Δ V necessary to escape the central body (having grav. param. equal to μ ) when the one-impulse maneuver is performed at true anomaly θ , in the velocity vector direction. For which true anomaly value is this Δ V minimum? Optional problem 2 (on tangential vs. normal maneuver): Solve problem 6.28 page 384 of textbook (current edition). 1...
