Title: Innovations by Nicholas C Donnangelo

Introduction

Nicholas C Donnangelo is an accomplished inventor based in Leesburg, VA (US). He holds three patents that showcase his expertise in aviation technology and safety. His innovative contributions have the potential to significantly enhance aircraft operations and safety measures.

Latest Patents

One of his latest patents is an aircraft icing sensor. This sensor utilizes a surface gap transmission line along which a radio frequency is transmitted. The phase delay of the radio frequency along the transmission line is dependent upon the dielectric constant presented at the surface in the gap between the transmission line electrodes. Changes in dielectric constant affect the phase delay of the transmitted frequency. This phase delay can be used to detect the difference between ice, water, and snow, as well as the presence of freezing point depressing fluids such as ethylene glycol. When mounted on an aircraft control surface, the sensor can predict the presence and likelihood of icing conditions. By using temperature data and the rate of change of the dielectric constant, it is possible to predict the time delay until icing begins. This innovation may safely reduce the effort and expense involved in aircraft deicing.

Another significant patent is an airborne surveillance method and system. This system allows an observer aircraft to determine the position and change of position of multiple target aircraft, enabling analysis of potential collision threats. The system employs a phase comparison direction-finding antenna to ascertain the direction of nearby ground-based SSRs and all target aircraft of interest. It utilizes various data, including Mode C transponder-generated altitude information, to determine the position of target aircraft. The system compensates for the observer aircraft's attitude and employs optimal Kalman filtering to produce accurate estimates of target positions while accounting for measurement errors.
