The patented Airfoil Performance Monitor (APM) provides real-time information to pilots regarding the state of the airflow over the aircraft's wings and tail. This information is critical for the prevention of stalls and Loss of Control (LOC), particularly during airborne icing encounters.

According to a 10-year National Transportation Safety Board (NTSB) study, LOC was the leading cause of fatalities in large commercial jet and business jet aircraft, accounting for 4,717 lives lost and 44% of all U.S. business aircraft accidents during a ten-year period. Many LOC events are caused by airfoil stalls that result when the airflow becomes turbulent and separates from the airfoil. This can result in severe aircraft controllability and performance difficulties. Traditional angle-of-attack (AOA) stall-protection systems use horizontally mounted weather vanes that are fuselage-mounted and cannot detect the state of the airflow over the wing. In contrast, APM detects the flow separation caused by an impending stall at its source.

“Marinvent Corporation is tremendously honored that its patented Airfoil Performance Monitor (APM) was recognized as the winner of the Aerospace & Defense Category. We are certain that this special recognition will significantly increase public awareness of the problem areas identified by the NTSB, while highlighting the role that APM can play in drastically reducing future accidents and fatalities.”

APM uses miniature pressure transducers to measure air turbulence that has been shown to correlate closely to stall proximity, regardless of icing. APM has the demonstrated capability to drastically reduce stall-related LOC accidents, with significant lifesaving potential.

APM has equal application to manned and unmanned vehicles of all sizes. APM can be used to directly monitor and optimize aircraft cruise performance, resulting in significant gain in fuel efficiency and reduction in greenhouse gases. The design is mature and production-ready, based on flight-quality, commercially available sensors and electronic components.

Breathing System for Divers Based on Separation of Dissolved Air from Water

Alan Bodner,
Tsafon, Israel

Based on the amount of dissolved oxygen that exists in seawater, the human oxygen consumption rate, and the amount of energy required to release dissolved oxygen in sufficient amount, a non-nuclear submarine could supply the needs of oxygen for its crew by extracting the oxygen from the water. This method can replace the current air supply system (storage in cylinders) with the advantage of much longer underwater capacity.

Hybrid Miller Cycle Rotary HCCI Engine for RQ-7 Class Drones

Roderick Newstrom,

This engine design eliminates spark plugs or diesel fuel injectors via Homogeneous Charge Compression Ignition (HCCI). Magnets, combined with coils in the radial housing, effect a motor/generator for starting, re- verse, rapid acceleration, power gen- eration, hybrid operation, and occasional silent running. Ignition delay is minimized, and the stroke and inertial loads associated with the rapidly moving piston are reduced.

Ultra-High-Speed, Magnetically Levitated Reaction Wheels for Small Satellites

Arda Tuysuz, ETH Zurich,
Zurich, Switzerland

A magnetically levitated reaction wheel with an integrated electrical drive, magnetic bearings, and sensors allows for a compact sys- tem for small satellite attitude control. The same materials are utilized for both the magnetic bearings and the rotational drive, enabling ultra-high-speed operation. Low-speed reac- tion wheels using ball bearings can be replaced with this reaction wheel with minimum effort.
