UAV Propulsion Tech – Post #11 – UAV Engine Suppliers

UAV Engine Suppliers (UPDATED NOV 27, 2017):

Full disclosure at the front of this blog is I represent AeroSteyr/Hirth and they will be detailed in this list as well as my competitors in this market.  Some people may think I shouldn’t promote my competitors but I think it is good to highlight the options available in this market.  Each supplier has their own advantages and disadvantages and it all depends on what the UAV manufacturer needs.  Some want an off the shelf solution while others are looking for a custom solution designed around their requirements.  Some want to run on gasoline and some want to run on heavy fuel (Jet A, JP5, JP8).   You combine the size, weight, power, noise, fuel consumption, and cost requirements and it can be a real challenge to find a consumer off the shelf (COTS) solution.

I am going to supply a list below with some general info on the suppliers as well as their website links where you can go to get more info.


Hirth Motors – Stuttgart, Germany – www.hirth-engines.de and also on my website at www.uavpropulsiontech.com/hirth.
