The core of the ACHEON thrust and vector propulsion is a nozzle with a duct eventually bipartite into two internal channels, which converge in ... WebHigh RPM, or low blade pitch is analogous to a low gear - each revolution of the prop requires little power, so you get high RPM. Each revolution results in little forward thrust, because the pitch is low, and the blade bites into the air at a shallow angle. Low RPM, or high pitch, is analogous to a higher gear, for cruise.
