Rocket Propulsion:

Theory: Β· Rocket motion is based on Newtonβs second law of motion ( πΉ = ππ ). Β· Rocket motion is a variable mass problem i.e rocket mass changes as the propellant is used up. Β· Air density varies with altitude. Β· In flight, a rocket is subjected to four forces: thrust, lift, drag, and weight. Governing equations: 1. Drag equation π·πππ πππππ = πΆπ βππ΄π£/ 2 Where: a) Cd=drag co-efficient (obtained from the NASAβs Glenn Research Centre website) b) Ξ‘=air density (I used the ISA model because using the standard ideal value of 1.2kg/m3 would not reflect the practical air density conditions encountered during rocket flight) c) A= rocket area (frontal) N/B: the area...
