  • Patent number: 10671091
    Abstract: When an unmanned aerial vehicle flies in accordance with a planned route that is set in advance on the basis of a position of a GPS receiver measured by a measurement unit and the measurement accuracy detected by a measurement accuracy detection unit has decreased to be less than a predetermined value, a flight control unit performs control so that the unmanned aerial vehicle flies along a route different from the planned route. Moreover, when flying along the planned route lowers the measurement accuracy, the unmanned aerial vehicle is caused to fly along the route different from the planned route. Therefore, the flight can be continued while the position is measured with the measurement accuracy secured.

  • Patent number: 10336471
    Abstract: A method for designing an aircraft includes defining an initial catalog of requirements for at least one aircraft design. An optimization of the at least one aircraft design is carried out based on the catalog of requirements in terms of anticipated operating costs. A predefined total flight network is simulated with the at least one aircraft design and a total flight network efficiency is determined. It is then checked as to whether the determined total flight network efficiency constitutes an optimum. The catalog of requirements is adapted and an iteration is performed upon a determination that the determined total flight network efficiency does not constitute the optimum.

  • Patent number: 8886366
    Abstract: Device and method to estimate the state of a moving vehicle overflying a certain terrain. The device comprises a camera oriented toward the terrain, an inertial measurement unit, a device for the processing of images and a “navigation filter”. This filter uses an innovative method to obtain state estimates of the vehicle. Unlike the conventional art, only robust and flexible expressions are used here, producing accurate state estimates, with no possibility of divergence, with no need for initial state estimates or high computational power. The method calculates parameters describing geometrical relationships among points of the trajectory and others on the terrain. These parameters are combined with estimates of the accelerations to obtain estimates of the velocity at a given time and of the gravity acceleration vector. By integrating these estimates, velocity and position profiles are obtained. The state is expressed in a reference system fixed with respect to the terrain.

For example, a vertical profile and a horizontal trajectory are determined, with the horizontal trajectory being non-linear so that the energy of the aircraft can be sufficiently dissipated before final approach along an approach axis, while also avoiding obstacles. Thus, a flight trajectory is determined even when the aircraft has deviated from a flight plan and approach axis.

In an alternative embodiment, the takeoff rotation guidance indicator includes a slip-skid symbol. The slip-skid symbol is positioned relative to aircraft reference symbol, but is displaced by the lateral acceleration of the aircraft.

    Abstract: An automatic trim system and method is disclosed for automatically trimming a flight control surface of an aircraft. A force sensor measures a force applied by a pilot to a flight control system actuator. The length of time that the force is applied by the pilot is then timed by a timer. A trim system to reduce the applied force is included on the flight control surfaces. A processor determines if trim is required if a predetermined amount of time is exceeded based on the force sensor measurement. The processor can set the trim system to the trim required therein. An airspeed sensor is used to verify that the aircraft has sufficient speed for flight. A force sensor can be utilized to measure the input force being applied by the pilot. If a pilot input force is applied to the controls and the aircraft is in a steady state, a timer can be activated.

  • Patent number: 8711035
    Abstract: Apparatus and methods determine the rotational position of a spinning object. A satellite positioning system can be used to determine the spatial position of an object, which in turn can be used to guide the object. However, when the object is spinning, such as an artillery shell, then the rotational orientation should be known in order to properly actuate the control surfaces, such as fins, which will also be spinning.

  • Patent number: 8712606
    Abstract: A system and methods for configuring a direct lift control system of a vehicle are presented. A plurality of fly-by-wire control surfaces is provided, and fly-by-wire control surface deflection commands of the fly-by-wire control surfaces are scheduled. The fly-by-wire control surfaces are symmetrically actuated based on the fly-by-wire control surface deflection commands such that a fluid dynamic lift of the vehicle is modulated without using a short-period pitch control.

  • Patent number: 8682510
    Abstract: A method for determining the distance of an aircraft from an offset runway during a landing by offset approach, the offset runway being situated at a distance D from a main runway equipped with at least one elevation beacon, comprises at least the following steps: determining the height h at which the aircraft is situated, height determined with respect to a point T1 of the offset runway, height measured by a radioaltimeter with which the aircraft is equipped, determining the angle of elevation ? of the MLS mode by using the information of the elevation beacon provided by an elevation beacon with which said main runway is equipped, determining the value of the distance ? of the aircraft from the azimuth beacon (10) by using the following formula ? = ( h Tan ? ( ? ) - D ? ? 2 Cos ? ( ? ) ) 2 + h 2 , and, using said distance ? to obtain a point of location of the aircraft in an offset runway reference frame.

  • Patent number: 8670881
    Abstract: A flight management system is provided for generating a variable thrust cutback during aircraft departure. The flight management system includes memory storing a sound exposure level limit for a navigation flight and storing expected sound exposure levels for an aircraft, and one or more inputs for receiving sensed aircraft variables including altitude and airspeed. The system also includes a processor for processing the sensed altitude and airspeed and stored sound exposure levels. The processor further computes an engine thrust value that complies with the sound exposure level limit based on the altitude, airspeed and the sound exposure levels for controlling aircraft throttle during departure.
