In Situ Algorithms

Winds Derivation Algorithm – also known as the Inertial Wind Recovery Algorithm (IWRA), provides an estimate of the three-component wind and turbulence gusts derived from measured aircraft parameters. The algorithm is non-aircraft specific in its estimation of the outputs. A commercial ship system version of this algorithm is available that only uses those parameters that can be obtained from current air data systems on typical commercial aircraft. This algorithm provides an accurate representation of the wind field experienced by an aircraft.

Winds-Based EDR Algorithm – also known as the Winds-Based In Situ Algorithm is considered the ‘truth’ measurement of the eddy dissipation rate (EDR), because it is aircraft configuration and flight condition independent. The EDR is calculated from RMS filtered winds derived using the Inertial Wind Recovery Algorithm and  a ircraft speed.    A commercial ship system version is  also available using only parameters available on  current air data systems on typical commercial aircraft .

Running R.M.S. Calculation Algorithm – calculates the standard deviation of the input data series using a moving window method. AeroTech has performed the Running R.M.S. calculation on normal accelerations, calculated wind values, and on in situ algorithm outputs.

Smoothing Algorithm – designed to filter the noisy signals from the ships systems that are used in calculations  for the In Situ Algorithms .

8th Order Digital Bandpass Filter – is a Chebyshev bandpass filter.

Rigid Body Response Algorithm – calculates the distributed load throughout the cabin of an aircraft.

Synthesis of Angular Acceleration Vector Algorithm – differentiates aircraft rotational rates to synthesize the components of the angular acceleration vector .
