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.
