ABSTRACT:
A multi stage high-altitude data acquisition system comprising a first stage manned lighter-than-air, engine propelled aircraft and a second stage air-buoyant vehicle of stratospheric altitude attaining capability statically sustainable aloft by a sufficient quantity of lighter-than-air gas contained within an expandable envelope balloon to carry the vehicle to a stratospheric float altitude and transportable from ground level to a tropospheric launching altitude by the first stage aircraft from which the air buoyant vehicle and its partially expanded gas containing envelope is releasable at the launching level while the first stage aircraft is established in a flight condition of substantially zero airspeed. The first stage aircraft preferably is a rigid type airship having a silo within an interior bay of the airship of dimensions and configurations as will retain within the airship the air-buoyant vehicle and its lifting gas envelope partially expanded to a volume displaced by the lifting gas at the lower troposphere launching altitude.
