It doesn't take innovation to bolt engines on that are not rated for that purpose, have warnings in the T.O.s about not using them for that purpose, and repeatedly fail during testing at that purpose.

The whole project is a capital B Bad Idea, but I'm honestly wondering what caused them to have problems with uncommanded shutdowns on those engines. They're the turbine equivalent of two-stroke weed-whacker engines: so simple they shouldn't just fail like that. I'm thinking their fuel system was a hilarious clusterfuck, with odd aerodynamic interactions at the intake face being a close runner-up.

From the Twerp Report:quote:The engines each have an ECU, an engine display (Jeti), a fuel pump/controller, and a throttle. The engines came with Lithium Iron batteries. During the ground run and taxi phase we had several uncommanded shut downs of engines while idling. The manufacturer thought that this could be related to one of two things bus voltage or to interference going between the engines via our added bus tie. The bus tie connected the left and right buses to reduce the risk of a battery failure causing an engine failure. This installation was the first time two TJ-40s had been run on the same vehicle. The engines were run with and without the bus tie turned on and no difference in engine reliability was observed so it was decided we should look at bus voltage. The engine’s built in starter generator would not generate enough electricity to support the engine at low power settings. As a result care was taken to run the engines at or above 20% power after start to recharge the battery before a take-off or taxi was attempted. We found this drastically increased the reliability of the engines. Our pre-flight procedure was to run the engine at greater than 20% for 2 minutes before takeoff. After doing this we had no more uncommanded engine shutdowns, except for one that was attributed to the pilot accidentally pulling the throttle past the idle gate.

hobbesmaster posted:Based on the flight in the video would it be fair to say that he had nowhere near enough yaw authority to put two engines on the plane? Yes, probably, but there's more things wrong with it. The single engine isn't quite powerful enough to climb with. When you have this situation in a twin, you basically have a single engine aircraft with double the chance of an engine failure. So a good setup would be more powerful engines, which would induce even more yaw. When you read development histories, it's pretty common to see "the B-model had a bigger rudder for more single engine yaw authority". Fate is the hunter. It prods you for your weak spots and always finds them.

What is interesting is that the exact moment the engine flames out is different in that video than it is on the other video on the Red Bull website, which has the pilot explain what happened. https://www.redbull.tv/video/AP-1QPD5KQXS1W11/crash-aftermath?playlist=AP-1MSW4H6YW1W11:extras The aircraft also begins its yawing motion to the left exactly as the left main wheel touches down before the flameout, which is probably his decrab. The turbulent airflow into the port engine due to beta as a result of this was the cause of the subsequent flameout, according to the pilot. hobbesmaster posted:Based on the flight in the video would it be fair to say that he had nowhere near enough yaw authority to put two engines on the plane?

This is ERAU. They departed singly, flew a four-mile upwind, a three mile base, departed at a 45° angle from the base leg, and then all requested flight following at the same time.
