Patent ID: 7438259

Claim:
A compound aircraft, said compound aircraft comprising: a. a fuselage; b. a main rotor rotatably connected to said fuselage, said main rotor being configured to exert a main rotor lifting force to said fuselage; c. a wing connected to said fuselage, said wing being configured to exert a wing lifting force to said fuselage, said main rotor and said wing in combination being configured to exert a total lifting force to said fuselage; d. means to select an operational objective by a user of the compound aircraft from among a plurality of operational objectives; e. an inceptor, said inceptor being configured to receive a command for a trimmed flight; f. a microprocessor, said microprocessor being operably connected to said main rotor and to said wing, said microprocessor being operably connected to said means to select said operational objective and to said inceptor, said microprocessor being configured to receive said selected operational objective from said means to select said operational objective, said microprocessor being configured to receive said command for said trimmed flight from said inceptor; g. a computer memory operably connected to said microprocessor, said computer memory storing a database accessible to said microprocessor, said database including a plurality of combinations of trim settings, each of said plurality of combinations of trim settings being configured to achieve said command for said trimmed flight when applied by said microprocessor, a one of said plurality of combinations of trim settings corresponding to said selected operational objective, said microprocessor being configured to select said one of said plurality of combinations of trim settings corresponding to said selected operational objective, said microprocessor being programmed to allocate said total lifting force between said rotor lifting force and said wing lifting force for said trimmed flight, said microprocessor being programmed to base said allocation of said total lifting force for said trimmed flight upon said selected one of said plurality of combinations of trim settings.
