Final LOHAN spaceplane test mission codenamed PRATCHETT

We're gearing up for the final avionics test flight of the Low Orbit Helium Assisted Navigator (LOHAN) project, and have dubbed the mission PRATCHETT ("Planes Reactive Airborne Tests Checking Heuristically for Extreme Technological Tantrums") in honour of the late…See More

LOHAN high-altitude test flight in Exmaps

We're obliged to the chaps down at Exmaps for sticking the data from a Low Orbit Helium Assisted Navigator (LOHAN) test flight into their "Drone Flight Logbook". The virtual two-hour High Altitude Ballooning (HAB) mission makes for…See More

"The latter. They work fine for the purposes of HIL."

"what's going on with the canards? they seem tremendously deflected in flight. Was that a design choice or just xplane not reflecting reality?"

Vulture 2 spaceplane HIL simulation

We've been quietly beavering away at hardware-in-the-loop simulations for our Vulture 2 spaceplane, and Pixhawk wrangler Linus Penzlien has finally got the aircraft to land itself at a virtual Spaceport America.The HIL work involves ArduPilot controlling an…See More

Brett Smith commented on Lester Haines's blog post Results in from Vulture 2 avionics stratospheric test flight
"I was under the impression that most off the shelf GPS units do not work at this altitude, but obviously this is not the case. Do companies (like ublox) put any firmware restrictions so they do not operate at certain altitudes/velocties???"

"No comms on this flight - just logging data on the SD card."

"Hi - Yes, space blanket works, but we're more concerned about electronics overheating at altitude. The internal temperature isn't much of an issue, if the batteries can handle it."

Matthew R commented on Lester Haines's blog post Results in from Vulture 2 avionics stratospheric test flight
"I've wondered if lining the case with aluminized mylar as a radiative heat reflector would help. I experimented with an emergency space blanket recently, and its effect was really noticeable in my living room. It's also very,…"
