Abstract
Anti-fogging systems for air-cooled, piston powered single engine aircraft which effectively prevent windshields from fogging during cold weather by directing a forceful stream of unheated, ambient air in a direction which intercepts exhaled air from an aircraft occupant to impede the moist exhaled air from directly reaching the windshield and condensing on the windshield. The disclosed systems keep the windshield of a small air-cooled, piston powered single engine aircraft from fogging while permitting a pilot to perform his pre-flight preparation, taxi and takeoff in cold climates.
Claims23
An anti-fogging system in an air-cooled piston engine aircraft, said aircraft comprising a cabin, a dashboard, an instrument panel comprising a rearwardly facing surface, and a windshield;
- said dashboard positioned at least partially below said windshield;
- said anti-fogging system comprising at least one electrically powered blower;
- said blower connected to at least one air conduit to collectively form a continuous air passage from an inlet end to an outlet end;
- said inlet end of said air passage positioned below said dashboard to receive ambient cabin air;
- said outlet end of said air passage configured to direct said ambient air stream rearwardly of said windshield;
- wherein said air passage does not comprise a heater or other mechanism for altering the temperature or humidity of the ambient air;
- and
- wherein, in operation, said blower creates a forceful stream of ambient air which exits said outlet and directly intercepts exhaled air from an occupant to prevent exhaled air from directly reaching said windshield.
An air-cooled, piston engine airplane comprising;
- an air-cooled engine;
- a firewall;
- a cabin separated from said engine by said firewall;
- a windshield;
- at least one seat in said cabin for an occupant and positioned for supporting said occupant in a position to allow visibility through said windshield with said occupant's face positioned rearwardly of and spaced from said windshield;
- a dashboard;
- an instrument panel comprising a rearwardly facing surface;
- said anti-fogging system comprising at least one electrically powered blower located in said cabin,
- said blower connected to at least one air conduit to collectively form a continuous air passage from an inlet end to an outlet end;
- said inlet end of said air passage positioned below said dashboard to receive ambient cabin air;
- said outlet end of said air passage configured to direct said ambient air stream in a direction which is rearwardly of said windshield and forwardly of said occupant's face;
- wherein said air passage does not comprise a heater or other mechanism for altering the temperature or humidity of the ambient air;
- and
- wherein, in operation, said blower creates a forceful stream of ambient air which exits said outlet and directly intercepts exhaled air from said occupant preventing it from directly reaching said windshield.
An anti-fogging kit for installation in an air-cooled piston-powered, single engine aircraft comprising a windshield, said anti-fogging kit comprising:
- at least one electrically powered blower located in said cabin,
- said blower connected to at least one air conduit to collectively form a continuous air passage from an inlet end to an outlet end;
- said inlet end of said air passage positioned below said dashboard to receive ambient cabin air;
- said outlet end of said air passage configured to direct said ambient air stream in a direction which is rearwardly of said windshield and forwardly of an occupant's face;
- wherein said air passage does not comprise a heater or other mechanism for altering the temperature or humidity of the ambient air;
- and
- wherein, in operation, said blower creates a forceful stream of ambient air which exits said outlet and directly intercepts exhaled air from an occupant preventing it from directly reaching said windshield.
