Flight Testing the Martin Jetpack in New Zealand
Test Pilot Prospero “Paco” Uybarreta
Thursday, 28 August 2025
12-1pm
Webinar: https://aiaa.zoom.us/j/85883591985?pwd=08PKe0CJqg9KbVXLVgobq81rUIs31i.1 Passcode: 055522
The Martin Jetpack was a single-person aircraft that used ducted fans for lift. Martin Aircraft Company of New Zealand (not related to the Glenn L. Martin, US company) developed it and unveiled it at the EAA 2008 AirVenture in Oshkosh. The FAA classified it as an experimental ultralight airplane. It used a gas engine with two ducted fans to provide lift. It was specified to have a maximum speed of 25 mph, a flight ceiling of 2,500 ft., a range of 12.5 mi, and endurance of about 28 minutes of flight. Empty weight was 440 lb. Martin Aircraft initially planned to target first responders as customers but the company shutdown in 2019. Paco will describe the amazing program and his test flights that he accomplished as its test pilot.

Effect of Rotating Detonation on a Ramjet Inlet in Mach 4 Free-Jet Experiments
Wednesday, 17 September 2025

A hydrogen-fueled rotating detonation ramjet was tested in the TUSQ wind tunnel at conditions corresponding to Mach 4 flight at 15 km. The purpose of the experiments was to demonstrate the engine operation, assess the effect of rotating detonation on a ramjet inlet and define the conditions at which the inlet unstarts. Fluctuations of Pitot pressure, measured with a probe outside the engine cowl, coupled with schlieren imaging, were used to detect inlet unstart. Four modes of combustion were identified, which primarily depended on nozzle contraction ratio and equivalence ratio, namely: deflagration, started rotating detonation, unstarted rotating detonation, and pulsed detonation. Started and unstarted rotating detonation modes were achieved at lower nozzle contraction and equivalence ratios. In both rotating detonation modes, a single detonation wave was observed, propagating at circumferential velocity of 45% to 63% of Chapman-Jouguet model (normal velocity of 64% to 89% assuming detonation wave propagating at 45 deg). It was found that a periodic inlet unstart and pulsed detonation phenomena were coupled. Potential cause could be either periodic auto-ignition or flame-holding attributed to the backward facing step. For both deflagration and detonation, an unstart occurs at similar isolator exit pressure of about 530 kPa.
