Abstract
An aircraft fuel delivery system having a first tank for storing a first fluid, second tank for storing a second fluid and a shut-off valve. The shut-off valve includes a first inlet port for introducing the first fluid into an internal valve chamber and a second inlet port for introducing the second fluid into the internal valve chamber such that the second fluid can be combined with the first fluid to create a fluid mixture. The shut-off valve also includes a valve member the position of which can be adjusted for controlling the delivery of the first fluid and/or the fluid mixture to the aircraft power plant.

An aircraft fuel delivery system comprising:
- a first tank for storing a first fluid;
- a second tank for storing a second fluid;
- a first line in fluid communication with the first tank;
- a second line in fluid communication with the second tank;
- and
- a shut-off valve comprising:
- a valve housing having an internal valve chamber;
- a first inlet port in fluid communication with the first line for introducing the first fluid into the internal valve chamber;
- a second inlet port in fluid communication with the second line for introducing the second fluid into the internal valve chamber such that the second fluid can be combined with the first fluid to create a fluid mixture;
- an outlet port in fluid communication with a delivery line for conveying the first fluid or the fluid mixture from the internal valve chamber to an aircraft power plant;
- and
- a valve member for controlling delivery of the first fluid and/or the fluid mixture to the outlet port.
A method of delivering a fluid mixture to an aircraft power plant, the method comprising:
- providing a first tank containing a first fluid;
- providing a second tank containing a second fluid;
- providing a shut-off valve having an internal valve chamber;
- introducing the first fluid and the second fluid into the internal valve chamber;
- mixing the second fluid with the first fluid within the internal valve chamber to create a fluid mixture;
- and
- delivering the fluid mixture from the internal valve chamber to the aircraft power plant.
