Merlin negative G cutout too quick?

[Crumpp]

Yep, its probably almost instantaneous

No probably to it, it is instantaneous. A Merlin engine sucks ~40-130 gallons per hour....there is not enough gas in the float bowl to fire the cylinders through one complete cycle.

Read the document again. Cut out occurs when it hits .9G on a mechanical dial gauge accelerometer. An acelerometer reads 1G at wings level or on the ground.

It only takes .1G of negative acceleration as measured on a mechanical dial gauge accelerometer to induce cut out.


That is 1/10th of a G...

By all means read that small amount of accelerations accurately on a dial gauge please.....

The correct answer is "when the needle moves, cut out occurs...." That is what you see in the air with a float carburetor.
