Study of the minimum anti-icing energy based on icing limit state

Abstract

This paper presents a new approach for calculating aircraft anti-icing heat load based on the icing limit state in which all the heat fluxes outside the skin can reach equilibrium without additional heat supplied to the skin and there is just no ice formation. Different from the conventional method with the assumption anti-icing surface temperature a constant value (e.g. 4℃ or 20℃), this paper takes the surface temperature distribution in the icing limit state to calculate the anti-icing heat load of the flight state, which can avoid the randomness of the assumed temperature value and provide a theoretical reference for aircraft anti-icing heat load calculation. Relevant calculation code is developed with VB.NET language. This paper calculated the minimum anti-icing heat load of DFVLR-4 airfoil in numerous cases and compared the results with those whose surface temperature is 10℃ and 20℃. Results show that the approach in this paper can not only meet the requirements of anti-icing but also save energy on the aircraft in a certain extent.
