A system includes an engine cover covering a side-facing rotorcraft engine and having an opening and an ice protection member mounted on the engine cover between the opening and the engine, an area of the ice protection member smaller than an area of the opening. The ice protection member is configured to partially cover the opening to prevent ice having a particular size from entering into the engine and to allow air flow downstream into the engine.

A manned unmanned teaming (MUM-T) image system includes an unmanned vehicle (UV) configured to travel in a first heading and includes at least one sensor configured to capture at least one image having a first visual orientation pursuant to the first heading. The MUM-T image system generates image data indicative of the at least one image. A manually operated vehicle (MOV) in signal communication with the UV is configured to travel in a second heading. The MOV comprises an electronic image transformation module configured to receive the image data and to transform the image data into a second orientation different from the first orientation based on the second heading. An electronic display unit is configured to receive the transformed image data and to display the at least one image according to the second orientation.
摘要:
A power plant comprising two engine groups and a main power transmission gearbox. Each engine group drives the main gearbox mechanically in order to rotate a main rotor of an aircraft at a frequency of rotation NR. A first engine group comprising two main engines is regulated on a first setpoint NR* for the frequency of rotation NR, while a second engine group comprising a secondary engine is regulated on a second setpoint W2* for power. The second setpoint W2* for power is determined so that each secondary engine operates only when a flight power Wvol necessary for the flight of the aircraft is greater than the sum of the main maximum powers WMax1 from each main engine.

A method of data collection from a rotor system of an aircraft includes positioning a plurality of sensors at a plurality of locations of a rotating portion of the rotor system. One or more antennae are located at one or more rotationally fixed locations of the aircraft. Rotor system data is collected via the sensors and is wirelessly transmitted from the sensors to the antennae and is transferred from the antennae to a gateway where it is normalized and synchronized. In another embodiment, a data collection system for a rotor includes a plurality of sensors located at rotating locations of the rotor, the sensors configured to collect and wirelessly transmit rotor data. Antennae are located at a fixed location of the aircraft. The antennae are configured to send and receive data from the sensors. A gateway is connected to the antennae to normalize and synchronize the rotor data.

Systems and methods using an Unmanned Aerial Vehicle (UAV) to perform physical functions on a cell tower at a cell site include flying the UAV at or near the cell site, wherein the UAV comprises one or more manipulable members; moving the one or more manipulable members when proximate to a location at the cell tower where the physical functions are performed to effectuate the physical functions; and utilizing one or more counterbalancing techniques during the moving ensuring a weight distribution of the UAV remains substantially the same.
摘要:
A rotorcraft including a fuselage, one or more motor-driven rotors for vertical flight, and a control system. The motors drive the one or more rotors in either of two directions of rotation to provide for flight in either an upright or an inverted orientation. An orientation sensor is used to control the primary direction of thrust, and operational instructions and gathered information are automatically adapted based on the orientation of the fuselage with respect to gravity. The rotors are configured with blades that invert to conform to the direction of rotation.

A system and method to tilt coaxial counter-rotating rotor hub assemblies relative to a fuselage. The system includes a first rotor hub assembly and a second rotor hub assembly spaced apart from the first hub assembly and carried by the fuselage. The method includes pivotally attaching the first rotor hub assembly and the second rotor hub assembly to a pivot joint and thereafter tilting the first rotor hub assembly and the second rotor hub assembly about the pivot joint with a driver.

The present invention discloses a vehicle (1) capable of being converted between a flying condition and an automotive riding condition. The vehicle has a telescopically extendable tail (10) comprising a first tubular tail segment (11) and a second tail segment (12) disposed axially slideable within the first tubular tail segment. The tail is provided with at least two form-closing coupling members (21, 35; 31, 36) located at an axial distance (LI) from each other for providing a force-transferring coupling between the second tail segment (12) and the first tubular tail segment (11) in the extended state of the second tail segment (12), each of said form-closing coupling members (21, 35; 31, 36) capable of transferring torque and transverse forces, and each of said form-closing coupling members (21, 35; 31, 36) coming into engagement by axial displacement of the second tail segment (12) in the outward direction.

A single engine rotary wing aircraft is provided including a fuselage having a longitudinal first axis. A main rotor assembly is mounted to the fuselage for rotation about a second axis, perpendicular to the first axis. A tailboom is connected to an empennage. The tailboom is mounted to an end of the fuselage such that the tailboom is laterally offset from the first axis in a first direction. The rotary wing aircraft also includes a propulsion system. The single engine of the propulsion system is laterally offset from the first axis in a second direction opposite the first direction.
