Introduction To Multi Engine Aerodynamics — CFI Steph
The accelerated slipstream behind the engine at full power encounters the gear and creates excess drag and that drag helps to counter the turning tendency. So both flaps up and gear up will negatively affect your Vmc speed.

2024年10月5日 · Accelerated Slipstream (Roll and Pitch) Asymmetrical thrust (P-Factor) results in a longer moment arm to the center of thrust of the right engine than the left engine. Therefore, the center of lift is farther out on the right wing, resulting in a …
P.A.S.T Critical Engine / Vmc - Airliners.net
2007年9月12日 · Hello, I am posting here to get some help on figuring out how P-Factor, Accelerated Slipstream, Spiraling Slipstream, and Torque define the left engine as the critical engine in conventional twins that have both props rotating clockwise from cockpit view. Another factor apart of Multi-Engine flying I am interested in learning about is Vmc.

2024年7月6日 · In multi-engine planes, each engine’s propeller creates its own slipstream—a rapid stream of air pushed back by the rotation of the propeller. When an aircraft is in accelerated flight modes, such as takeoff or climb, the slipstream is more intense and can affect the aerodynamics of the aircraft significantly.
Roll- Induced flow (Accelerated Slipstream- extra lift created by accelerated air over the wing) from the operating engine and lack of induced flow from the inoperative engine causes asymmetric lift on wings. This results in a rolling moment around …

2007年12月6日 · Accelerated slipstream is a rolling tendency resulting from P-factor. The wing generates more lift directly behind the propellers then in other areas due to increased airflow from prop wash. Since P-factor shifts the center-of-thrust towards the descending blade, it also shifts propwash and, as a result, lift by the same distance.
What Exactly Is Accelerated Slipstream Effect? - Airliners.net
2002年5月27日 · Regardless, it happens because the clockwise rotation of the propeller (from inside the cockpit) sends the air spiraling around the plane: First under the fuselague, then up over the horizontal stabalizers, and then directly onto the rudder from the left. The resultant push to the right forces the nose left, adding to the left turning tendancy.
Accelerated slipstream (or induced flow) is extra lift created by air accelerated from an operating engine forced over the wing. There is a lack of this induced flow over the wing with the failed engine. This results in a rolling moment around the C.G. toward the inoperative engine.

2010年10月24日 · Asymmetrical lift due to accelerated slipstream effects varies with AOA and may or may not significantly affect controllability at speeds approaching Vmc. 4). Except for airplanes such as the Beech 18 (for obvious reasons), spiraling slipstream plays no part whatsoever as it does not affect airflow across the vertical stabilizer in flight.
