A rocket motor is used to accelerate a kinetic energy weapon to a speed of 3500 mph in horizontal flight. The exit stream leaves the nozzle axially and at atmospheric pressure with a speed of 6000 mph relative to the rocket. The rocker motor ignites upon release of the weapon from an aircraft flying horizontally at U0=600 mph. Neglecting air resistance, obtain an algebraic expression for the speed reached by the weapon in level flight. Determine the minimum fraction of the initial mass of the weapon that must be fuel to accomplish the desired acceleration.
Carbon fibre reinforced polymers (CFRP have been used extensively in aerospace applications due to their excellent strength to weight and stiffness to weight properties.
