WebConsequently, you would want a small exit diameter. 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! Web3 hours ago · Welcome to Edition 5.33 of the Rocket Report! Phew, there is a lot going on this week.
