Nozzle Design - NASA

Nozzle Design - NASA

a rocket engine uses a nozzle to accelerate hot exhaust to produce thrust as described by newton's third law of motion. the amount of thrust produced by the engine depends on the mass flow rate through the engine, the exit velocity of the flow, and the pressure at the exit of the engine. the value of these three flow variables are all determined by the rocket nozzle design.

Build Your Own Thrust Vectored Rockets For Vertical

if you love rockets, you can’t help but notice that real space launch vehicles lift off the pad slowly,but model rockets zip up like darts. that’s how i became obsessed with using thrust vector control (tvc) — gimbaling the rocket motor — instead of fins to keep model rockets upright, so they can launch, and land, far more realistically.

keep in mind this isn't how i might build a small rocket engine, but a compromise (earlier, kaito suggested essentially dumping the propellant into the chamber through two opposing pipes). earlier i suggested a more conservative design, machined out of multiple thick pieces of metal and fitted together with screws, which kaito didn't like.

Engineering | Hybrid Rocket Engine Project

hybrid rocket engines are prone to having a low fuel regression rate relative to solid fuel rockets due to the chemical differences between the fuel grains used. this low regression rate may necessitate the use of several fuel ports, which comes with its own set of design challenges (addressed in the volumetric loading fraction sub-section below).
