The Nimbus H80 is designed as a UAV powerplant with special attention given towards bearing cooling and lubrication. The bearings are fitted in such a way as to be resistant to skidding and damage during high G loads from manoeuvring and catapult/rocket-assisted launches. Bearing replacements can be done by the operator on site without requiring a full engine stripdown with minimal training. The accompanying operation manual gives full details for maintainence intervals and procedures.

The Nimbus H80 is available with full autostart ECU and can be running at idle in 15 seconds from cold. It has a long shelf life of up to 10 years when stored in a clean environment. All parts are manufactured from corrosion-resistant materials that can withstand hot humid climates without degradation. The internal components are all produced from corrosion resistant materials for the central shaft tube assembly, the turbine nozzle ring is a one piece casting from inconel which gives far superior dimentional stability and heat resistance that other similar designs. Now available with direct kerosene start.

To obtain the most reliable operation, the Nimbus H80 has propane starting nozzles and kerosene for normal running.

The maximum thrust is 100lb for short periods (take off etc) and up to 80lb for maximum continuous running.

Idle thrust is 4lb and acceleration time from idle to full speed is within 4 seconds.

Fuel consumption at 80lb thrust is 0.9lt/ minute.

The Nimbus H80 is also ideal as a powerplant for experimental projects. We can modify the H80 to your specifications upon request to accommodate airframe requirements and craft design, amongst others.

These photos show two of our latest engine called the H80T placed each side of a standard H80 (all without starter motors attached). Externally almost identical to the H80 appart from a slightly larger compressor inlet face and larger jetpipe housing.

The H80T can currently develop up to a maximum thrust of 110lb with more to come from future versions.

CIRRUS H65

This is the smaller brother of the H80. It has the same casing diameter but is slightly shorter and lighter.

The max thrust from the Cirrus is 65lb or up to 75lb for short durations. The idle thrust is 2.5lb.

The SFC is 1.23lb/hr/lb at 65lb thrust. And operates with the same autostat ECU and fuel pump as the H80.
