Introduction

Jeffrey S. Mattice, an accomplished inventor based in Enfield, CT, has made significant strides in the field of helicopter technology. With a total of four patents to his name, Mattice's innovations focus primarily on engine control systems and rotor torque prediction, which are crucial for enhancing helicopter performance and safety.

Latest Patents

Two of Mattice's latest patents include an advanced engine control system and a rotor torque predictor. The engine control system is designed for helicopters and features components that generate a power turbine speed signal based on a demanded rotor speed. This system utilizes a high-order filter to rapidly attenuate main and tail rotor torsional frequencies, ensuring no loss of phase at low frequencies. Additionally, it includes a governor for maintaining isochronous power turbine speed and rotor speed control based on the filtered signal.

The rotor torque predictor presents a novel approach to determining the total torque required at both the main and tail rotors of helicopters. This system implements a polynomial neural network that predicts aerodynamic torque during flight, taking into consideration multiple pilot and airframe inputs. By analyzing main rotor speed and collective stick position for hover conditions, along with main rotor speed and pedal position for stationary conditions, the rotor torque predictor efficiently calculates the necessary torque for optimal rotor function.
