摘要： An unleaded aviation fuel blend. The fuel blend is provided by blending an unleaded aviation gasoline base fuel which may include iso-octane and iso-pentane, and an effective amount of a selected alkyl benzene to improve the functional engine performance to avoid harmful detonation sufficient to meet or exceed selected standards for detonation performance requirements in full scale aircraft piston spark ignition engines designed for use with Grade 100LL avgas. Advantageous alkylated benzenes include those having a meta-ring position between alkyl groups. Alkyl groups may be provided at least in part by methyl groups. In an embodiment, the alkyl benzene may include 1,3-dimethylbenzene. In an embodiment, two or more alkylated benzenes may be provided. In an embodiment, 1,3,5-trimethylbenzene may be provided. Suitable alkylated benzenes may include a mixture of xylene isomers. Selected aromatic amines, such as m-toluidine, may also be added to increase motor octane number.

摘要： An emergency descent system for turbocharged piston engine powered aircraft. The flight management system is configured to challenge the pilot after a period of inactivity. Acknowledgment from the pilot resets the timer for subsequent challenge. Lack of timely pilot response sets off an alarm sequence. Lack of response to the alarm sequence sets off emergency descent by way of control by the flight management system of rate of descent, heading, ground track, and engine power by adjustment to the wastegate to the turbocharger. The control by the flight management system may incorporate direct control of the aircraft airspeed in the descent, and that may be enhanced by engine power adjustments. Upon reaching a selected target altitude, the aircraft engine power may be restored via the adjustment of the wastegate controller. At any time, when the pilot regains useful consciousness, the entire emergency descent sequence may be interrupted and normal control restored by the pilot. Additionally, the system may be configured to reset the aircraft transponder to an alarm code, in the event that the emergency descent sequence is initiated.

摘要： A full time lean air fuel mixture running spark ignited air cooled aircraft piston engine. In one embodiment, a drop-in substitution is provided for an equivalent make, model, and engine size, wherein the new, rebuilt, or reconfigured engine provides as much or more horsepower when compared to the original engine, but runs at a lean air fuel ratio condition during normal operating modes, including takeoff, climb, and cruise, thus saving significantly on fuel. In yet another embodiment, a drop-in substitution having a somewhat larger cylinder displacement volume may be provided to attain equivalent or enhanced maximum horsepower while operating at lean air fuel ratios. Enhanced engine life may be anticipated, since cylinder head temperatures (CHTs) may be reduced, compared to engines using rich air fuel ratios for climb and cruise conditions. Aircraft using such engines are also disclosed.

摘要： Unleaded aviation gasoline. High quality aviation alkylate, or similar base fuel is blended with selected alkyl benzenes to improve the functional engine performance to avoid harmful detonation in aircraft piston engines. Monoalkylated benzenes such as toluene and ethylbenzene are utilized in combination with dialkylated benzenes, such as xylenes. Aromatic amines, for example p-toluidine and m-toluidine, may be added to increase MON. Alcohols such as ethanol and/or methanol may be added in effective amounts to produce unleaded AVGAS which meets a required freeze point. Amounts of toluene to p-toluidine, and/or of the amount of p-toluidine to m-toluidine may be in a controlled ratio in amounts effective to produce unleaded AVGAS which meets a required freeze point. Isopentane and/or butane may be included to provide a required vapor pressure profile. Manufacturing may be achieved using an additive concentrate including aromatic solvents, aromatic amines, and alcohols.
