PBS Aerospace
Even with all the recent interest in small turboprops, there is but one place to burn kerosene in the build-it-yourself world. The SubSonex single-seat jet is the one available airframe and the Czech PBS TJ100 turbojet is the one engine that airframe is designed for. It’s the only jet engine in production with the thrust, size and availability to fit the sport aviation bill.
PBS does not disclose technical or pricing information without a non-disclosure agreement, so we’re unable to report directly on the little jet. SubSonex builders can order the PBS engine from Sonex, which lists the PBS engine on their website with full supporting hardware for $74,000. And if you have something spectacularly brief in mind, the TJ100 is available in a higher output version with a 100-hour TBO. Bang!
Suggestions welcome for a source of a used or surplus gas turbine 15-30 kW APU or GPU to be used for alternate fuel experiments by individual experimenter (me). Prefer (any) electrical output, but I can convert a hydraulic or mechanical output into electricity. Thank you for any ideas.
