Hi Paul,
sounds not too bad: 2 rotors + 52 kW/6000 + ~ 28 pds net weight.
Of course, you will need some auxiliary "devices" for the engine.
Guess, this RE will be very expensive.
But, it looks good ;-)
Best regards

Looks like a scaled down Mazda except that the front middle and rear outer housings
are all one piece. If so that is a major advance in cost of manufacture and service.
Quite doable in fact on almost any NC machine

Here is the earlier version. Looks like direct injection.
"KS: The Sky Power engines are all equipped with twin sparks as well as
with the ECU030 or the high-performance HKZ 215 ignition. Moreover, the
SP-110 FI TS possesses a newly developed injection. For these, we need a
lot of data to adapt the engine to the environment. This happens via
the ECU. Furthermore, we achieve better fuel combustion with the HKZ
2015. All in all, it’s possible to say that we’re achieving a massive
reduction in fuel consumption through these measures."
"The SP-110 FI TS was equipped with the new ECU030 injection and the new HKZ215
ignition. “Thanks to the two new systems, the engine can be tuned exactly to
environmental conditions as well as to the customer’s wishes”, explains Karl Schudt,
managing director of Sky Power GmbH. The ECU030 injection system is usable for both
gasoline mixtures and HF applications. The system has four ignition channels with two
separately settable injection nozzles. Pump pressure is regulated electronically. A
cold-start function of the engine is possible without further ado. The automatic
controller adjusts the fuel mixture to the current cylinder temperature, air
pressure, and exterior temperature. All of the engine’s data can be monitored via a
PC and can be readout by a CAN-BUS-interface. The user interface is intuitively
constructed so that all of the engine’s settings can be easily carried out."
"The high-performance HKZ system was developed for significantly greater ignition
powers. The engine’s overall fuel efficiency is thereby enhanced and the exhaust
values improved. All of the add-on components, such as connector plugs and spark plug
connectors, are designed and shielded for challenging application areas. “With the
new ignition and injection system, we achieve better power performance in 3W
engines”, explains Karl Schudt. Fuel reductions at constant power proved achievable
during test runs with the 3W-110i B2 TS FI. Thus a fuel reduction by more than 20%
was achieved at 5500 rpm. “The results aloft also surprised us, but they clearly show
what is possible in the area of efficient fuel and engine management”, according to
Karl Schudt. Sky Power is also offering to convert propulsion systems already in use
on the market. For this purpose, the engine has to be sent in to the new service
centre in Germany."
I would hardly call it a massive reduction in fuel consumption.
I see no hint of turbo compound :-) They will be very lucky to get
below .47. I see no sign of intake tuning either so the results at any
one RPM are meaningless. Intake tuning is essential.
