We captured a time-lapse video of our third-generation Boomerang Balloon Valve venting helium at 15,000m (49,200ft) over the Willamette Valley.This valve has been designed to operate in the cold conditions of the stratosphere and provide high-flow rates at low pressures.
Earlier this year we developed and tested a “Passive-Parachute Deployment System” (P-PDS) for the Boomerang Balloon Altitude Control System. Below is a video outlining the rationale and testing of the system.
We did a low-altitude ballooning test flight of our Generation 2 Boomerang system back in July in the Alvord Desert. The test flight was a proof of concept for the Boomerang system. We performed a series of maneuvers to demonstrate float stability and rapid vertical rate changes. Because there is no relative wind noise, one can hear the sound of vent valve, the ballast release mechanism, and the sound of our chase car.
