Abstract:

This project deals with a unique solid-state, low-cost, rugged ice detection system
to reduce the hazards of aircraft icing. This system will sense an impending wing-stall
condition of an aircraft by directly measuring the intensity of turbulent airflow
induced by ice accretion. The key system components are piezoelectric transducers
for sensing boundary-layer pressure fluctuations and a microcomputer for digital
signal processing. The incorporation of a wireless data link will enable simple implementation
of a non-intrusive system easily retro-fitted on aerodynamic surfaces, engine inlets,
and fuel tanks. Flight tests will be performed on a Grumman AA-5 aircraft with simulated
leading edge ice to demonstrate system feasibility. If successful, this work will
lead to the development of an operational ice detection system during the Phase II.

Potential Commercial Application:

Potential Commercial Applications:  The product could be a low-cost sensor for de-icing
systems of current and future aircraft fleets, both civilian and military.
