Transcribed Image Text:Advanced Physics
As it turns out, the B-52 was carrying a
Pegasus launch vehicle. The Pegasus
starts with an initial velocity of 500mph;
it then accelerates with three engine
stages as below. Assume the rocket
uses Orion engines that account for the
entire structural mass except for the
added payload of 30kg and a fairing
that weighs 10kg.
The Orion family of solid-state motors
exhibit an isp of 220s, and their masses
are as below; all masses listed below are
given in kg. The final stage deploys the
payload and fairing release mechanisms.
Each stage separation occurs without a
change in velocity.
Stage 1) Orion-50s
13,405 full, 950 empty
Stage 2) Orion-50
3,370 full, 320 empty
Stage 3) Orion-38
890 full, 110 empty
Assuming that atmospheric losses
amount to an equivalent velocity
reduction of 2km/s what is the final
velocity of the payload?
