Flywheel energy calculator

Interesting tool for working out energy generated by flywheel fro a given RPM, weight and radial distance

Matt,

It is still with Malcolm and Francis at the LAA. I expect there will be some developments very soon.

an interesting read of harmonic balancers which is related to the problems we see in the jabiru setup.

hello Dominique,

The LAA has approved the first phase (fitting and testing) of the modification. Testing will begin early May and likely to be complete towards the end of the month. All parts for the modification are available. I have the nordlocks, longer bolts and pressure plate available.

Re: Flywheel compression ring - Nordlock X washers

Update 02/06/15

1.5 hours Ground running was completed on 1st of June and results were unremarkable with only slight loss of bolt tension attributed to the settling of components. We are in the final phase of testing.

The LAA has released a Permit to test fly the mod (2.5 hours flight testing at different power settings).

I shall be conducting flight testing this coming week end.
