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.
Claims17
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 positioned at an angle to horizontal;
- 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 untreated ambient cabin air;
- said outlet end of said air passage comprises baffles which are angled relative to the angle of the windshield to direct a stream of untreated ambient air rearwardly of said windshield and not toward said windshield;
- wherein said anti-fogging system does not comprise a heater or other mechanism for altering the temperature or humidity of the untreated ambient air;
- and
- wherein, in operation, said blower creates a stream of untreated ambient air which exits said outlet and directly intercepts exhaled air from an occupant to prevent exhaled air from reaching said windshield directly from an occupant.
An air-cooled, piston engine airplane comprising;
- an air-cooled engine;
- a firewall;
- a cabin separated from said engine by said firewall;
- a windshield positioned at an angle to horizontal;
- at least one seat in said cabin for an occupant and positioned for supporting an occupant in a position to allow visibility through said windshield with an occupant's face positioned rearwardly of and spaced from said windshield;
- a dashboard;
- an instrument panel comprising a rearwardly facing surface;
- and
- an 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 untreated ambient cabin air;
- said outlet end of said air passage comprises baffles which are angled relative to the angle of the windshield to direct a stream of untreated ambient air rearwardly of said windshield, not toward said windshield, and forwardly of an occupant's face;
- wherein said anti-fogging system 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 stream of untreated ambient air which exits said outlet and directly intercepts exhaled air from an occupant preventing exhaled air from reaching said windshield directly from an occupant.
