Our 3.0 litre displacement current test platform engines have produced astounding performance at 3000 rpm: 282 Nm/208lbf torque and 89kW/119hp on Jet A1. At over 9.8Bar this represents comparable BMEP to some current production aircraft engines. But the key significance and advantage is the fact, that those numbers were achieved with a spark ignited Duke Engine running on kerosene based Jet A1 fuel, not on Avgas. This possibly makes the Duke Engine the first practicable Spark ignition 4-stroke engine capable of achieving speeds and power comparable if not better than competitive reciprocating engines currently used in aircraft and larger UAV's.
Operating on Gasoline, we achieved 317 Nm/234lbft @3500 rpm which at 11Bar/160psi BMEP equates to 116 kW/156hp.
Our engine is not yet optimised for power, weight or size yet and so we expect more significant improvements in the near future.
We are preparing our engines for another round of testing in the US at the dyno facilities of our co development partners in Detroit.
We are currently negotiating with potential partners to integrate our engine technology into their platforms and solutions. We are open to development and application programmes, co manufacturing and licensing and are excited to be able to offer a solution for the current need for a kerosene/jet fuel propelled light weight aviation engine with lots of power density. Our engine's cylindrical shape and light weight, together with low vibration and unique aerodynamic advantages our engine is easy to integrate in any platform and offers great potential.
We will shortly post the latest test progress results to date - including a comparisons between current production engines, our latest test results and targets for the near future.
