the COSH(control of static heaviness)

The fourth dimension of flight.
a new paradigm in air transport is born with the advent of the Aeroscrat - an aircraft that utilizes a combination of buoyant and dynamic lift creating unique operational capabilities beyond of what is available from any other air platform today. In distinct contrast to hybrid airship concepts, the Aerosscraft has the ability to manage its own lift depending on the stage of flight.

The united states government Defense Advanced Research Projects Agency(DAPRA) launches the statigic lift Walrus program selecting Aeros as a Prime Contractor.

Aeros Completes the Flight Demonstration of the Buoyancy Management System.
The COSH(Control Of static Heaviness) System works by compressing, storing then decompressing helium within the envelope to adjust the vehicles's buoyancy. Static heviness is the ratio of buoyancy to gravity; it is increased to land and reduced to takeoff

Aeros performs flight demonstrations of the low speed control system.
The low speed control system, is designed to allow for a full yaw/drift authority to the pilot in cross winds at all flight phases at any flight speed, in addition to landing in extremely short and narrow landing sites.

Aeros completes the DAPRA BAAV demonstration program.
During successful Structure integrity testing, Aeros confirmed that, in a full scale vehicle, a rigid aerostructure satisfies loads requirements without failure.

The Aeroscraft Vehicle Flight Management unit system bench test has been completed.

The Aeroscraft Vehicle Flight Management is a dual redundancy "flight-by-light" system that is based on advanced fiber optic tecnology that makes it lighter weight and immune to electric noise.

Aero begins assembly of the Aeroscraft.
The assembly process was marked by the first two structural truss components being put together.

Conceptual Study of the Aeroscraft ML8XX completed.

Aeroscraft ML866 Development Program Begins.
Program ML8XX is renamed to Aeroscraft Model ML866

First buoyancy assisted air vehicle,Aeroscraft ML866 development program announced at the NBAA 60th convention.

Aeros begins working on Certification Basis for the new type of air vehicle Aeroscraft Model ML866.
