Award List:

Windage Loss Reduction for High Speed Electrical Machinery

Award Year / Program / Phase: 2008 / SBIR / Phase I
Agency / Branch: DOD / USAF
Principal Investigator: Erik E. Swanson, President/Chief Engineer
Award Amount: $97,414.00
Abstract:
The efficiency of electric motors and generators operating with high rotor surface speeds is reduced due to viscous shear and aerodynamic effects. These losses are generally referred to as "windage loss." In some specific, high speed machines of particular interest to the aircraft community, it… More

Low-Cost Ball/Air/Magnetic Hybrid Bearing System for Extended-Life Micro Gas Turbine Engines

Award Year / Program / Phase: 2010 / STTR / Phase I
Agency / Branch: DOD / NAVY
Research Institution: Widener University
Principal Investigator: Erik Swanson, President/Chief Engineer
Award Amount: $69,579.00
RI Contact: Joseph J. Baker
Abstract:
Micro gas turbine engines with state-of-the-art ultra-compact recuperators could be a real game-changer for small unmanned air vehicles and portable power generation. A key enabling technology for these engines is a low-cost, high speed bearing system that has long life, while operating without… More

Windage Loss Reduction for High Speed Electrical Machinery

Award Year / Program / Phase: 2010 / SBIR / Phase II
Agency: DOD
Principal Investigator: Erik Swanson, President/Chief Engineer – (434) 296-6094
Award Amount: $749,135.00
Abstract:
Designers of modern, high speed electrical power generation machinery have had great success in increasing the overall system efficiency of these machines over the past few decades. These increases in efficiency are extremely important for applications in modern tactical aircraft, where any losses… More

Developing and validating a model to understand mixed lubrication regions for fluid-film bearings

Award Year / Program / Phase: 2012 / STTR / Phase I
Agency / Branch: DOD / NAVY
Research Institution: University of Colorado at Denver
Principal Investigator: Erik Swanson, President/Chief Engineer – (434) 972-9368
Award Amount: $149,242.00
RI Contact: Lora Mihelic
Abstract:
Seawater lubricated propulsor (i.e., stern tube) bearings are one of the most important bearings aboard a ship. The performance and life of these bearings directly affects the vessel's operational capabilities, life cycle costs, and overall availability. In a single shaft vessel such as an Ohio… More
