MAE 5540 - Propulsion Systems!

8530!


a) Continuous Small Thrust

Impulsive Delta V


Part a!

Burn 2! Burn 1:!Isp = 2000 sec!Fthrust = 10 Nt!

Continuous Small Thrust


a)

a)


1)  Assume Burn 1 is Continuous!

2)  Assume Burn 2 is Impulsive!

3)  Isp = 270 sec for both burns!

4)  Mfinal=1000kg!

Burn 1 !continuous!

Burn 2 impulsive!

Stephen Whitmore


Part b, Large Thrust Transfer Problem !

270 sec!


Burn 2! Burn 1:!Isp = 270 sec!Fthrust = 2000 Nt!
