"@Andrew - A mad idea, but strangely attractive. Doable, but we'd need a completely different launch set-up/release mechanism for such a flight - the latter being the big challenge. I'd go for 5,000m or so for starters, just to give the…"
"@Lester, when I told Rob and Randy about this project they raised the idea of also strapping a small quadcopter (maybe a 250 size?) to the payload, then releasing both plane and copter at the same time. It would then be a "plane vs copter"…"
"very cool project. Its got my mind racing with ideas.
ever considered the payload be a fixedwing drone?
launch up to 31k then see how far you can get lateraly?
*new to the forum. hope to learn a lot here*
"One of the major aims of the test flight was to test the comms link, so we could be confident of being able to control the aircraft in the final Lohan mission.
The radio setup was a RFD900 running at 27dBm on the ground station, with a 6dBi yagi.…"
"Next up the roll and pitch, giving us some idea of how much the balloon swung, and how much it swung on the chute after the burst.
Here is the overall roll-pitch graph against altitude (degrees of roll/pitch, altitude in meters above sea level)
"I've started having a look at the DF log from the flight. Here is a temperature plot from all the logged temperatures. The airspeed sensor got to -48 degrees C at an altitude of around 18km. The other sensors stayed much warmer as they are…"
"I think I would be inclined to shoe horn an NTX2B in there for some distributed tracking goodness. I can't remember is there one in the main aircraft? @Melih hyper pressurized floating balloon project Do tell more in another thread!"
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…
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…
