Transforming Passenger Aircraft into Firefighting Airtankers

A leader in aircraft conversion, our Commercial Aerospace teams are working on the world's first Boeing 757 firefighting airtanker for Galactic Holdings. The Boeing 757P2T (Passenger-to-Tanker) will be one of the largest aerial firefighting platforms, boasting a remarkable capacity of up to 7,000 gallons of fire retardant. Notably, it will also be more fuel efficient compared to current generation airtankers.

Meet Joyce Hoe, Senior Engineer from the design team behind the Boeing 757P2T prototype aircraft. She shares about her contributions to this innovative solution, which is currently in its final stages of engineering design refinement. 

Hi Joyce! Tell us about your role on the 757P2T programme.

Certainly! I focus on the structural modification design of the aircraft. This involves analysing and understanding the necessary changes to convert a passenger aircraft into an airtanker. I conceptualise and develop compliant designs for the aircraft's structural packages. Additionally, before physical modification of the prototype aircraft, I generate detailed 3D models and 2D production drawings and utilise simulation tools to assess our designs in virtual environments.

What aspects of working on this project did you find most enjoyable?

Coming from a maintenance background, I gained valuable insights into design engineering and got to appreciate the effort required to turn concepts into reality. The strong camaraderie within the team made work enjoyable. My colleagues are patient and ever-willing to share their diverse experiences and provide guidance when needed. The collaborative environment fostered seamless exchanges of ideas which were crucial for achieving the complex engineering requirements of our programme. 

What breakthroughs were achieved in designing the 757P2T?

Designing the 757P2T as an effective firefighting tanker required us to develop highly responsive door systems for mid-air fire retardant dispensing. We had to consider technical requirements, innovate creatively, and adhere to safety regulations. After several designs, simulations and checks, we managed to successfully modify the 757 to include two dispensing doors on the aircraft's belly, optimising retardant release and enhancing firefighting efficiency.

How does your work enable a more secure and sustainable world?

Our pioneering efforts on the Boeing 752P2T support global sustainability by extending the useful service life of retired passenger aircraft. Additionally, the project saves lives by enabling improved wildfire response capabilities, limiting damage to essential vegetation that serves as food and shelter to wildlife. Being able to work on this inventive solution that essentially safeguards both the planet and its vulnerable animals feels incredibly rewarding!
