We were asked by a plane manufacturer to examinate the possibility to increase flight duration with additional flexible tank.

The challenge

The challenge was:

  • flexible tank with 1200L capacity in addition to the one already there.
  • take into account the dimensions and tiny space in which we have to put our product.
  • the tank must fit with aviation rules, design and it needs to be as efficient as a normal  one.
  • the management quality system must suit with standard aviation rules

Our engineering tea, in partnership with customer’s team have followed technical specifications, which were required such as : speed, break, life length. All of this in order to deliver a prototype at first and then many series of product.

Vulcanisation has been the key point on which we can rely on. Indeed thanks to this process and tailor made tools, we have successfully passed the customer’s qualification.

  • the dimensions are very important because we need to settle this tank into a very incommodious space
