Thrust Equation - Glenn Research Center NASA
WebMay 13, 2024 · Te / Tt = [1 + Me^2 * (gam-1)/2]^-1. Knowing Te we can use the equation for the speed of sound and the definition of the Mach number to calculate the exit velocity Ve : Ve = Me * sqrt (gam * R * Te) We now have all the information necessary to determine the thrust of a rocket. The exit pressure is only equal to free stream pressure at some ... Web3 hours ago · Welcome to Edition 5.33 of the Rocket Report! Phew, there is a lot going on this week.

However, in my experiments I measured the thrust of a 12x12 inch propeller at around 5500 rpm and got 20 N without a nozzle (just a constant diameter duct) and only 4 N with a nozzle reducing the exit diameter to 50 percent of the prop diameter. These results are contrary to my theory! orange clove lotion
