Method For Regulating The De-Icing Of A Leading Edge Of An Aircraft And Device For Its Implementation

摘要

A method of regulating the de-icing of a leading edge of an aircraft includes regulating the flow of air used for de-icing by at least a first regulator valve in accordance with two regulation levels, a first regulation level corresponding to the regulated position of the first regulator valve and a second regulation level corresponding to the fully open position of the first regulator valve. A de-icing device enables implementation of the regulation method.

主权项

1. A method for regulating the de-icing of a leading edge of an aircraft, said method employing a de-icing device including a duct for routing a flow of hot air from a hot air source to at least one outlet and a regulator device for regulating said flow of hot air including:
a first regulator valve regulated pneumatically with a single first regulation level and controlled by a first controller setting said first regulator valve in accordance with a fully open position and a regulated position at a first regulation level, and a second regulator valve regulated pneumatically with a single second regulation level and controlled by a second controller setting said second regulator valve in accordance with a fully open position and a regulated position at the first regulation level wherein the regulation method comprises: regulating the flow of air in accordance with two regulation levels, a first regulation level for which the first controller sets the first regulator valve to the regulated position or in the event of a malfunction of the first regulator valve the second controller sets the second regulator valve to the regulated position, and a second regulation level for which the first controller and the second controller respectively set the first regulator value and the second regulator valve to the fully open position of both regulator valves.
