Is there an optimal flight path angle for the ballistic missile option? 2.5 Typical ballistic missiles have a burnout height of 100 miles with a maximum range of 8000 miles. How much extra Av capability would be required to use the missile as a launch vehicle to orbit payloads in polar orbits (90° inclination) at the 100 mile altitude? 2.6 A small interceptor is launched horizontally from an aircraft flying at M = 0.8 at an altitude of

2.5

Answer 1

Given data: Burnout height, h=100 miles Range, R = 8000 miles Altitude, = = 100 miles The height of the polar orbit from the earth surface is 500 miles, therefore the missile has to travel the distance of 500-100 = 400 miles The difference in the velocity required is calculated as Av= 2xgx(Ah) = /2x0.00608 (500-100) = 2.20 miles/sec Therefore, the difference in the velocity required is 2.20 miles/sec).
