In a neutral burn for a solid rocket, thrust does what over time? (increases, decrease, remains constant) Remains constant This kind of rocket is often referred to as the safest kind of rocket, combining both solid fuel and liquid oxidizer. Hybrid Rocket 00:54 01:25 In a progressive burn for a solid rocket, thrust does what over time? (increases, decreases, remains constant) Increases In a regressive burn for a solid rocket, thrust does what over time? (increase...

Thrust T = ma Thrust term (pe - pa) > 0 Drag term (pe - pa) < 0 Overexpanded Nozzles have pressure losses (drag penalty) Underexpanded Nozzes have gains (thrust contribution) matched condition The highest thrust is generated when nozzle expansion ratio operates such that pe = pa Impulse Total momentum change imparted during a burn Specific Impulse Total Impulse/Weight of propellant Isp A measure of fuel efficiency; a measure ...
