Fuel pump certification

Fuel pump certification

Shaun Williams

As part of a larger product improvement activity, our team of specialist engineers worked with a client to develop and qualify a new fuel transfer pump designed to improve the overall fuel system reliability.

 

The project

As part of an aircraft certification programme our team of specialist engineers worked with a client to develop and qualify a new fuel transfer pump designed to improve the overall fuel system reliability.

The transfer pump was changed from an existing brushless Direct Current (DC) motor design that contained an electronics pack to rectify the variable frequency of the Alternating Current (AC) power supply; to a simpler induction motor design that operates directly off the variable frequency AC power supply. As a result, the new transfer pump had a more variable fuel transfer rate, now dependant on supply frequency, when compared to its predecessor.

  • WEC specialist engineers collaborated with the client and equipment supplier to develop and define the tests necessary to demonstrate the new pump satisfied the relevant requirements.
  • WEC were required to work as part of a trans-national team to develop and define appropriate tests. The test programme was required to provide evidence to support the demonstration of compliance with requirements at both equipment and system level.
  • Equipment level tests included: hydraulic, endurance, thermal, explosion proofness, electrical (including lightning) and vibration.
  • System level tests included: transfer rate at various operating conditions, reprime, defuel rate, unusable fuel and normal operation. System level performance was also investigated.

The benefit

Upon completion of the testing, WEC engineers analysed the test results and extracted the relevant data to demonstrate that the new pump complied with both the equipment and system level requirements that had been placed on the project.

Due to our extensive experience, and uncompromising commitment to professional integrity, WEC specialist engineers were able to add a layer of independence to the testing and wider certification activities. By efficiently and effectively meeting the project aims, we help our industry-leading clients to enhance system & platform reliability.
