RV-20?

Is that getting outside of what could realistically be done as a kit homebuilt?
Matt (?),

We have a 300hp engine in the pipeline. There will be a measure of commonality with the 200hp engine and given the traction we are getting with RV10 builders and more so, Raptor builders (if it makes it to market), the 300hp engine may be the follow on product to the 200hp engine.

With a SFC of approaching 0.9 lbs/hp/hr, the PBS Velka TP100 will only be for the turbine diehards (Admittedly, I am one of those but soon I will have my own engine with half that SFC ).

But, first order priority, get the 200hp established in the market, demonstrating reliability and safety, with the company building a base of happy customers.

Default Aerobatics

What do you imagine the aerobatics capability of the engine being? My dream to be putting it into an RV-8 and doing "gentleman's aerobatics". Inverted flight, loops, rolls, etc. What is likely to be the G limit, and other applicable limitations?

Hi David,

The engine is being designed to sustain a target of 9g with short duration overloads to 12g, in order to be suitable for aerobatics. The final g limitations will be determined following finalisation of the bearing system design and rotordynamic analysis.

Negative g should not be a problem. A suitable gearbox oil system will be offered.

Dave
