In late 2009 we will begin production of three different size, High Torque Multi-fuel Radial Piston engines which will be Air-cooled and Fuel Injected.

There are very few engine choices in the 65HP to 120HP range at the moment and Diesel engines in particular, are virtually non existent for Recreational Aviation use.

We have Patents for the engines already in place for some countries with more to be submitted in early 2009 to give us full world wide protection.

Below are the specifications for the three engine designs (all Diesel, but can be configured to run on UL petrol at slightly less HP). They will have inbuilt gear ratios and drive configurations. All engines have a maximum 3000rpm and are designed to have the following drive options;

(1) Direct drive (for fixed wing and Gyro's) for all three capacity engines
(2) Direct drive with counter rotating shafts (for helicopters, fixed wing and Gyro's) for all three capacity engines.
(3) Direct drive with 500rpm on front output of engine and 3000rpm on the rear (for Helicopters only) for the 1600cc and 2000cc engines.

The specifications are as follows;

CAPICITY ............HORSEPOWER.............. DIAMETER ............WEIGHT
1200cc .....................70HP ............................510mm ................<50kg
1600cc .....................95HP ............................610mm ................<65kg
2000cc .....................120HP ..........................710mm .................<80kg

Production cost estimates put these engines at around 15 to 20% less than currently available petrol engines (Rotax in particular) of similar horsepower and considering a diesel has 26% more power than a petrol engine of the same displacement, this makes our Radial Piston Diesel a very viable alternative.

We are looking for 'serious' comments from members regarding these engines. We will be relying on your feedback so that we can determine the viability for us to proceed with the production and general consensus that they will be readily accepted throughout the aviation community.

I have attached a photo of the Petrol version proof of concept prototype engine.

Looking forward to your comments.

Regards
Graeme
