It suggests that the top one-third slope will throw more residual thrust on the lower part, and there may be failures at the toe of the slope.
The top one-third part of studied slope has a sliding potential and poses residual thrust on the lower part.
The props are equipped with zero locks (and Beta range) so the only residual thrust
at idle is from the exhaust.
The key to power-off stalls is the power level: The throttle is set at idle, the engine producing no or only residual thrust
. Or the engine is stopped and you're flying toward a dead-stick landing.
All specified operating conditions and startup conditions should be evaluated for residual thrust
Finally, with the nozzles closed, a lot of residual thrust
came out of my idle engines.
Jet engines have significant "residual thrust
" that they make at idle.
The jet pipe of the engine incorporates a three-bearing swivel module (3BSM) that can turn the residual thrust
down through 95 degrees in 2.5 seconds, producing 80 kN of jet lift.
In any event, the engine happily provides some residual thrust
instead of drag, distorting the glide and speed experience compared to the numbers behind a dead engine with a windmilling fixed-pitch prop.
The residual thrust
is low, but occasional braking is required to prevent acceleration.
