Appl. No.:

15/427917

Assignee:

Telvent DTN LLC - Omaha NE

International Classification:

G08G 5/00

Abstract:

The DYNAMIC TURBULENCE ENGINE CONTROLLER APPARATUSES, METHODS AND SYSTEMS (“DTEC”) transform weather, terrain, and flight parameter data via DTEC components into turbulence avoidance optimized flight plans. In one implementation, the DTEC comprises a processor and a memory disposed in communication with the processor and storing processor-issuable instructions to receive anticipated flight plan parameter data, obtain terrain data based on the flight plan parameter data, obtain atmospheric data based on the flight plan parameter data, and determine a plurality of four-dimensional grid points based on the flight plan parameter data. The DTEC may then determine a non-dimensional mountain wave amplitude and mountain top wave drag, an upper level non-dimensional gravity wave amplitude, and a buoyant turbulent kinetic energy. The DTEC determines a boundary layer eddy dissipation rate, storm velocity, and eddy dissipation rate from updrafts, maximum updraft speed at grid point equilibrium level and storm divergence while the updraft speed is above the equilibrium level and identify storm top. The DTEC determines storm overshoot and storm drag, Doppler speed, eddy dissipation rate above the storm top, and determine eddy dissipation rate from downdrafts. The DTEC then determines the turbulent kinetic energy for each grid point and identifies an at least one flight plan based on the flight plan parameter data and the determined turbulent kinetic energy.

International Classification:

Abstract:

The DYNAMIC AIRCRAFT THREAT CONTROLLER MANAGER APPARATUSES, METHODS AND SYSTEMS (“DATCM”) transforms flight profile information, terrain, weather/atmospheric data and flight parameter data via DATCM components into comprehensive hazard avoidance optimized flight plans. Comprehensive hazard avoidance includes synergistic comprehensive turbulence and airfoil-specific icing data. In one implementation, the DATCM comprises a processor and a memory disposed in communication with the processor and storing processor-issuable instructions to receive anticipated flight plan parameter data, obtain weather data based on the flight plan parameter data, obtain atmospheric data based on the flight plan parameter data, and determine a plurality of four-dimensional grid points based on the flight plan parameter data. The DATCM may then determine comprehensive hazards mappings. With (near) real-time comprehensive hazard information and/or predictive turbulence/icing forecast specific to airfoil type and/or profile parameters, the DATCM may allow aircraft to avoid areas where comprehensive hazard is greater than a predetermined threshold and/or avoid areas where turbulence/icing may occur.

International Classification:

G01W 1/10

Abstract:

The DYNAMIC STORM ENVIRONMENT ENGINE (DSEE) transforms flight profiles, atmospheric data, and convective and non-convective turbulence predictions and observations into dynamic turbulence alerts, nowcasts, and optimized flight paths. The DSEE determines four-dimensional grid points for a temporal geographic area and determines atmospheric potential instability and potential turbulence intensity at each grid point. The DSEE masks potential turbulence intensity at least one grid point and determines and outputs at least one of the TKE and the total EDR for each grid point. In some implementations, the DSEE receives a flight profile for an aircraft, including an initial route. The DSEE can identify an initial predicted comprehensive turbulence for the at least one initial route and/or turbulence nowcast, and the predicted comprehensive turbulence and/or turbulence nowcast utilized generate a notification or exception, and/or are used to reroute the aircraft to avoid or minimize the effects of turbulence on the flight.

International Classification:

Abstract:

The AIRFOIL ICING CONTROLLER APPARATUSES, METHODS AND SYSTEMS (“AIC”) transforms weather and flight parameter data via AIC components into icing determinations and icing avoidance optimized flight plans based on airfoil type. In one implementation, the AIC comprises a processor and a memory disposed in communication with the processor and storing processor-issuable instructions to receive anticipated flight plan parameter data, obtain weather data based on the flight plan parameter data, obtain atmospheric data based on the flight plan parameter data, and determine a plurality of four-dimensional grid points based on the flight plan parameter data. The AIC may then determine a percent power increase (PPI) required by the aircraft to overcome power loss due to icing conditions. With dynamic, (near) real-time icing information and/or predictive icing forecast specific to airfoil type, the AIC may allow aircraft to efficiently avoid areas where PPI is greater than a predetermined percentage and/or avoid areas where dangerous icing may occur.
