WebConversely, if it is pitched for cruise, the static rpm will be low and takeoff will be sluggish. A further consideration is, the Lycoming O-360 is a high compression engine and does not like to be “lugged” — high manifold pressure and low rpm. Which is the condition you would have on takeoff with a fixed, high pitch prop. — Jim WebA combination of high manifold pressure and low rpm can induce damaging detonation.

WebMar 19, 2024 · Horsepower is torque x RPM. Reduce RPM, but maintain same torque (manifold pressure), HP goes down. Reduce torque, maintain RPM, and HP goes down. You'll find say, that 2300 RPM and 25" of MP make the same HP as 23" of MP and 2500 RPM. If it's a direct drive engine, prop RPM and engine RPM are the same.

WebReducing an aircraft’s propeller RPM causes a higher manifold pressure because as the RPMs decrease, the engine slows, creating less suction during the intake stroke which … WebMay 15, 2024 · If the throttle is closed and the engine is idling, the pressure shown on the manifold pressure gauge is at its lowest – usually around 12 to 15” Hg. When the throttle is wide open, and at maximum rpm, the pressure shown is highest, although still slightly lower than the surrounding air pressure.

WebMay 12, 2024 · The only regime I can think of, where a Merlin engine (supercharged) would reduce manifold pressure with increased rpm, are extremely low rpm, like idling on the runway. At these rotations, the supercharger is basically too slow to actually work.

WebSep 22, 2024 · It is possible to make a given amount of power using high manifold absolute pressure (MAP) and low rpm or by using low MAP and high rpm.
