ActiveUS6885917B2Easy to operateIncreases flight envelopeAircraft navigation controlDigital data processing detailsForward speedFixed wing
A method of stabilizing a jet-powered tri-mode aircraft as the aircraft travels in a helicopter mode, a compound mode, and a fixed-wing mode is disclosed. The method includes receiving a plurality of velocity vector component values and velocity vector commands derived from either (1) a number of pilot operated controllers or (2) a commanded array of waypoints, which are used for fully automated flights, and a rotor speed reference value, which is decreased with increasing forward speed to unload the rotor, thereby permitting conditions for stopping the rotor in flight. Stabilization of the commanded velocity vector is achieved in all modes of flight using blended combinations of rotor swashplate controls and aerodynamic controls such as elevons, canards, rudders, and a horizontal tail. Stabilization to the commanded velocity vector includes a plurality of control constraints applied to the pilot stick controllers that prevent penetration of envelope limits.

Compound helicopter
The compound helicopter is a hybrid combination of a helicopter and a fixed wing aircraft. A conventional helicopter is modified with a nose-mounted tractor propeller to provide thrust for forward flight. Wings are added to provide lift during forward flight. With the propeller providing thrust and the wings lift during forward flight, the helicopter rotor blades are unloaded during cruising flight to allow increased forward speed by avoiding limitations of conventional helicopters, including retreating rotor blade stall and maximum rotor blade tip speeds. A single powerplant drives both the main rotor and the nose-mounted propeller. The compound helicopter employs high aspect ratio wings with large flaps that may be extended to reduce vertical drag during vertical flight and hovering operations.

The invention discloses a verification method for information in a block chain network and a verification system thereof. The method comprises the steps that a first node in the block chain network monitors information broadcasted in the block chain network; the first node verifies the monitored information, and the first node signs the information if the verified information is legal information; the first node saves the signed information and forwards the signed information; a second node in the block chain network receives the signed information and verifies the information; the second node secondarily signs the information if verification is passed; and the second node saves the secondarily signed information and forwards the secondarily signed information. With application of the scheme, the workload of node information verification can be reduced and forwarding speed of the information can be accelerated so that the information is enabled to be more quickly forwarded.
