摘要:
A method of controlling a rotary wing aircraft includes accelerating the aircraft in a fore direction independently of cyclic control of the main rotor and pitch of the aircraft.
摘要:
The present invention relates to a device for generating aerodynamic lift and in particular an aircraft (100) for vertical take-off and landing. A wing arrangement (110) comprises at least one propulsion unit (111), wherein the propulsion unit (111) comprises a rotating mass which is rotatable around a rotary axis (117). The wing arrangement (110) is mounted to a fuselage (101) such that the wing arrangement (110) is tiltable around a longitudinal wing axis (112) of the wing arrangement (110) and such that the wing arrangement (110) is rotatable with respect to the fuselage (101) around a further rotary axis that differs to the longitudinal wing axis (112). An adjusting mechanism adjusts a tilting angle of the wing arrangement (110) around the longitudinal wing axis (112) under influence of a precession force (Fp) which forces the wing arrangement (110) to tilt around the longitudinal wing axis (112).

An aircraft having counter-rotating, ring-type wing rotors that are driven by engines (31) located at the wing tips is disclosed. The aircraft incorporates large span, high aspect ratio wings that are configured in a joined-tip design to improve the structural characteristics of the wings. One of the wings (13) counter-rotates inside the other wing (21) to enable vertical take-off and landing. The wings may comprise elliptical shapes, each having upper (15) and lower (17) sections that are separated from each other.

La présente invention concerne un carter supérieur (40). Le carter supérieur (40) comporte une coque (50) creuse en matériaux composites, ladite coque (50) présentant une paroi latérale (51) s'étendant en élévation d'une embase d'enveloppe (55) vers une collerette d'enveloppe (60), ladite paroi latérale (51) comportant au moins une découpe. La carter supérieur (40) comporte une doublure (70) interne qui est insérée dans la coque (50) et fixée à une face interne (53) de la coque (50), la doublure (70) comprenant une base (71) et un sommet (75), au moins deux jambes (73) s'étendant en élévation de la base (71) au sommet (75), la doublure (70) comprenant au moins un support d'équipement (80) au regard d'une découpe, chaque support d'équipement (80) étant destiné à porter un équipement amovible dudit carter supérieur (40).

摘要:
An aircraft is provided including an airframe, an extending tail, and a counter rotating, coaxial main rotor assembly including an upper rotor assembly with an upper blade and a lower rotor assembly with a lower blade. A first antenna in one of upper blade and the lower blade, and a second antenna in the other of the upper blade and the lower blade. An oscillator to apply an excitation signal to the first antenna. A blade proximity monitor to monitor a magnitude of the excitation signal and an output signal from the second antenna to determine a distance between the upper blade and the lower blade.
