Abstract
Official abstract text for this publication.
A method optimizing fuel-injection control with driving speeds of apparatuses adjusted by controlling a turbine speed according to power, and optimizing control of a free turbine power package of an aircraft, including a low-pressure body, supplying power to apparatuses and linked to a high-pressure body. The method varies the low-pressure body speed to obtain a minimum speed for the high-pressure body, so power supplied by the apparatuses remains constant. Power supplied by the apparatuses is dependent upon the apparatuses driven speed by the low-pressure body, and a speed set point of the low-pressure body is dependent upon a maximum value of minimum speeds of the apparatuses, enabling required power to be optimized, upon a positive or zero incrementation added to the speed set point of the low-pressure body to minimize speed of the high-pressure body to the apparatuses power supply.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for optimizing regulation of a free-turbine (TL) power unit of an aircraft provided with a low-pressure (LP) body which supplies power to an equipment and which is linked to a high-pressure (HP) body, the method comprising: determining a maximal value of minimal speed of the equipment; and setting an LP body speed set-point based on a sum of the maximal value of minimal speed and an increment to obtain a minimal HP body speed so that power s…
