Abstract:
A propulsion system includes an electric propulsor and a gas turbine engine. The propulsion system also includes an electric machine coupled to a rotary component of the gas turbine engine generating a voltage at a baseline voltage magnitude during operation of the gas turbine engine. An electric communication bus is provided electrically connecting the electric machine to the electric propulsor. The propulsion system additionally includes a means for providing a differential voltage to the electric propulsor equal to about twice the baseline voltage magnitude.
Abstract:
Die Erfindung sieht einen Elektroantrieb für ein Luftfahrzeughybridsystem vor. Dieser Elektroantrieb umfasst einen Rotor, einen Stator, wobei der Stator mit einer Struktur eines Luftfahrzeuges verbindbar ist und der Rotor einen ringförmigen Flansch mit einer Wellendurchgangsöffnung zur Befestigung an einem Propellerflansch aufweist, wobei der Flansch zumindest aus zwei Teilen ausgebildet ist, wobei ein jedes dieser Teile des Flansches einen Abschnitt der Wellendurchgangsöffnung begrenzt.
Abstract:
The present invention is a variable geometry aircraft that is capable of morphing its shape from a symmetric cross-section buoyant craft to an asymmetric lifting body and even to a symmetric zero lift configuration. The aircraft may include variable span, length, and camber. The variability of the structure and the flexible envelope allows the aircraft to adjust its aspect ratio along with the camber of the upper and/or lower surfaces to achieve varying shapes. This transformation changes both the lift and drag characteristics of the craft and may be accomplished while the craft is airborne.
Abstract:
Изобретение относится к области авиационного транспорта и может быть использовано в летательных аппаратах различных конструкций. Крыло летательного аппарата содержит несущую поверхность и турбореактивный двигатель. Несущая поверхность выполнена комбинированной из обычного аэродинамического крыла и жестко связанной с ним несущей пластины. Двигатель жестко крепится к несущей пластине так, что выходящая из него струя горячих газов обтекает ее верхнюю поверхность. Профиль несущей пластины повторяет профиль сопла Лаваля турбореактивного двигателя. Предлагаемая конструкция крыла призвана увеличить дальность, грузоподъемность и безопасность использования летательных аппаратов различного назначения.
Abstract:
Embodiments are directed to selecting, by a computing device comprising a processor, the size of at least one prime mover associated with an aircraft to satisfy a baseline power requirement for operation of the aircraft during a steady state load condition, selecting at least one power source configuration to supplement power provided by the at least one prime mover during a transient load condition associated with the operation of the aircraft, and selecting, by the computing device, a parameter of the at least one power source configuration to provide a total power in an amount that is greater than a threshold during the transient condition.
Abstract:
Aéronef convertible pourvu de deux rotors carénés en bout d'aile et d'un fan horizontal dans le fuselage. L'invention concerne un aéronef convertible comprenant un fuselage (F), une paire d'ailes (A1, A2) disposées de part et d'autre du fuselage (F), au moins un rotor caréné (1) installé en position horizontale à l'une des extrémités du fuselage (F), et une première et une deuxième nacelles (N1, N2) disposées respectivement à l'extrémité de chaque aile (A1, A2), comprenant chacune un rotor (R1, R2) caréné, et montées basculantes par rapport au fuselage (F), en ce qu'elles comprennent au moins un premier et un deuxième volets mobiles (V1, V2), disposés respectivement à la sortie du rotor (R1) caréné de la première nacelle (N1) et à la sortie du rotor (R2) caréné de la deuxième nacelle (N2). L'aéronef selon l'invention représente ainsi une solution avantageuse pour toutes applications impliquant des hélicoptères et des avions, et particulièrement les missions de sécurité civile, de secours, de transports publics ou privés.

Abstract:
A method for operating an aircraft that is driven forward in the air with a propulsion system in the form of two engines of the jet or propeller type one on each side of the fuselage is disclosed, and it is characterized in that during the forward movement of the plane, the two engines move in a mutual synchronous relationship with a longitudinal direction of the plane. Furthermore, the invention relates to an arrangement of such a propulsion system for aircraft operations. Moreover, the invention relates analog designs adapted for ships.
