Cyber Defense Successfully Tests New Propulsion System For Mid Altitude Airships

Airship Prototype.
St Petersburg FL (SPX) Sep 05, 2005
Cyber Defense Systems has announced the introduction and successful testing of a revolutionary new propulsion system. Cyber Defense's propulsion systems for the Mid Altitude Airships SA 90 being built by Techsphere Systems International is designed to maintain geo-stationary position at a cruise altitude of up to 25,000 feet.

The SA 90 under development is a semi spherical airship with the four engine CyberPOD propulsion system is designed for continuous operations 24 hour per day for a maximum of 2 days on station.

A critical subassembly of the propulsion system is the pylon assembly developed for the MAA program. This system incorporates an optimized large diameter propeller for the high altitude, low specific thrust airship conditions.

The support structure, mounting system, and articulating prop-drive has been analyzed extensively by finite element methods. A detailed forced harmonic life analysis of the structures attached to the semi-rigid structure has been performed, indicating a long life capability.

The 18-ft diameter custom propeller has been designed to operate efficiently for both MAA and High-altitude Airship ("HAA") M.A.R.S. Airship applications. Currently this propeller is machined from aluminum bar-stock, but the production-released version of the MAA and HAA will utilize light-weight composite blades of similar aerodynamic design.

"We are excited to introduce what we feel is an advanced airship propulsion system currently unavailable in the marketplace today," said Billy Robinson, CEO of Cyber Defense Systems.

"This new system will enable a heavier payload, will operate longer and more efficiently, and will be able to withstand severe weather conditions more effectively," added Mr. Robinson.
