Worldwide Aeros Corp. (Aeros, Montbello, CA, US) was granted a patent for the cargo airship’s flight system for a constant volume variable buoyancy air vehicle, with onboard control-of-static-heaviness (COSH) technology.
The technology enables the aircraft to engage in a broad set of new tasks including long-range, heavy-lift cargo transport. (See “Don’t call it a blimp!” from CW April 2014.)
“Large capacity airships have long been a dream for cargo logistics flexibility, but it was impracticable because if you off-loaded 100 tons, your helium filled aircraft will float away if not first loaded with 100 tons of ballast at your pre-determined destination. Inefficient and limiting, this is why airships never transition into cargo airships,” said Igor Pasternak, COSH inventor and CEO at Aeros. “This patent will permit only Aeros and our partners to leverage the empowerment of true VTOL in global heavy airlift, and the independence from off-board ballast and ground infrastructure this capability provides.”
According to Aeros, the COSH technology can bring new opportunities in global commercial logistics, military logistics and disaster relief response, among many others. Transport airships can potentially increase heavy cargo lift capability and destination alternatives, while reducing the current cost of air delivery on a ton/mile basis.
The patent protects Aeros’ proprietary technology for buoyancy management and flight principle empowering the Aeroscrat’s vertical takeoff-landing (VTOL) capabilities at maximum payload without ballast requirements.
The technology has been successfully demonstrated by an Aeroscraft prototype and will allow the Aeroscraft to operate as a lighter-than-air vehicle (LTA) when flying, yet become heavier-than-air when needed to accommodate weight changes during payload removal, and to also support ground operations.
