  • Patent number: 11125770
    Abstract: An acoustic air data sensor for an aircraft includes an acoustic transmitter, an acoustic receiver, an acoustic signal generator, timing circuitry, speed of sound determination circuity, and communication circuitry. The acoustic transmitter is located to transmit an acoustic signal through an airflow stagnation chamber that is pneumatically connected to an exterior of the aircraft and configured to receive and stagnate airflow from the exterior of the aircraft. The acoustic receiver is positioned at a distance from the acoustic transmitter to receive the acoustic signal. The pulse generator causes the acoustic transmitter to provide the acoustic signal. The timing circuitry determines a time of flight of the acoustic signal from the acoustic transmitter to the acoustic receiver. The speed of sound determination circuity determines, based on the time of flight and the distance, a speed of sound through air in the stagnation chamber. The communication circuitry outputs the speed of sound.

  • Patent number: 10823752
    Abstract: The angle of attack (AOA) of an airplane is calculated as the difference of the flight-path angle and the pitch angle. The pitch angle is available from an attitude monitoring device (e.g., pitch gyro), but the flight-path angle is not available from the basic instruments common in general aviation. This method determines the flight-path angle mathematically, and in particular, using inputs from indicated airspeed and GPS. The sine (trig function) of the flight-path angle is the value determined by dividing the vertical velocity, provided by onboard GPS, by the velocity along the flight path (e.g., indicated airspeed). The sine value is converted to the value of flight-path angle by referring to a sine lookup table.

    Abstract: Disclosed herein is a distributed pressure sensor system that quickly detects and counters changes in lift, onset of stall, and flutter. The distributed pressure sensor system may employ a plurality of integrated pressure ports distributed across the span of a wing's leading edge to gather differential pressure measurements. Based on the differential pressure measurements, the distributed pressure sensor system can estimate torque on the fuselage to provide a more efficient estimate for changes in lift, onset of stall, and/or flutter. These estimates may be applied as feedback to the aircraft's control system, thereby eliminating the latency in the existing platform dynamics.

    Abstract: A system and method involve determining the airspeed of a vehicle using the propagation time of an acoustic signal from a transmitter located at one end of the vehicle to a receiver located at the other end of the vehicle. A digital representation of the acoustic signal is created and stored within non-volatile memory within the transmitter, then converted into an electrical signal which is filtered, amplified, and input into a transducer contained within the transmitter. The transducer radiates an acoustic signal toward the receiver, which receives and filters the acoustic signal, converts it into a digital signal, and processes the digital signal to determine the acoustic signal propagation time. The acoustic signal may have a continuous wave form, a duty cycle of about 100%, a peak to average amplitude ratio of less than about 2.5, and Fourier components of substantially equal amplitude and random phase.

  • Patent number: 7817010
    Abstract: A temperature probe assembly is provided. The temperature probe assembly may comprise a housing formed of a first thermally conductive material and having an inner diameter defined by an inner bore, an insert formed of a second thermally conductive material disposed in the inner bore and having an outer diameter that is substantially equal to the inner diameter of the housing at a first temperature and a temperature sensor mounted within the insert. The second thermally conductive material has a thermal coefficient of expansion that is greater than the first thermally conductive material, such that the insert is insertable into the inner bore at the first temperature and is tightly locked in the inner bore at a second temperature that is greater than the first temperature.

  • Publication number: 20090320586
    Abstract: Systems and methods determine at least one air data parameter, such as an angle of attack (AOA), an angle of sideslip (AOS), a total pressure (pt), and/or a static pressure (ps), from information provided by four pressure sensors coupled to four ports on a surface of a vehicle. Each of the ports may be defined by at least a unit vector, wherein the unit vectors are oriented in different planes.

  • Patent number: 7389686
    Abstract: An air data system is described that includes a cone-shaped probe, a plurality of pressure transducers, and a processing device. The cone-shaped probe includes a first pressure port formed in a substantial tip of the probe and extending therethrough, and a plurality of pressure ports formed in a substantially evenly spaced circular pattern about a sloped surface of the probe and extending through the probe. The plurality of pressure transducers are each configured to receive at least one pressure transferred through at least one of the pressure ports and output one or more signals related to the pressures sensed. The processing device is configured to receive signals originating from the transducers. The processing device is further configured to calculate a static pressure, an angle of attack, and an angle of sideslip based on the received signals.

  • Patent number: 7334467
    Abstract: An air data module is provided that is relatively small, lightweight, low cost, uses relatively low power, and is relatively easy to install, test, and maintain. The air data module includes a housing that is adapted to be mounted to an external surface of an aircraft, and includes at least a sensor compartment and an interface electronics compartment formed therein. A pitot-static probe is coupled to the housing and extends therefrom, and has a static pressure passageway that is in fluid communication with the sensor compartment. A plurality of static pressure ports are formed in the pitot-static probe and are in fluid communication with the static pressure passageway. A pitot pressure inlet port is formed in a distal end of the pitot-static probe. A static pressure sensor and a differential impact or absolute pitot pressure sensor, for example, may be mounted within the module and used to sense static pressure and impact or pitot pressure, respectively.

  • Patent number: 7284420
    Abstract: An air data system and method for a rotary aircraft is described. The air data system includes a plurality of flush ports connected via tubing to a plurality of air flow sensors that can measure air flow speeds as low as approximately 0.02 knots. The flush ports are arranged around a main rotor shaft and below a rotor hub of the rotary aircraft to help reduce the impact of rotor downwash. The flush ports and tubing permit air to flow into the air flow sensors, which allows the plurality of air flow sensors to measure speed and direction of cross-wind components of air flow surrounding the rotary aircraft.

    Abstract: The invention relates to a device for ensuring safe movement of a moving part. The movement of the moving part is guided along or about an axis (4; 42) and is limited by at least one stop (1; 20; 51). The device comprises means for recording the exceeding of a nominal force by a force exerted on the stop (1; 20; 51) by the moving part along or about the axis (4; 42). The invention is particularly applicable to angle-of-attack sensors used in aeronautics.
