Abstract

An aircraft has an energy storage system comprising a first battery 6a comprising first and second battery modules 10, 11. A venting system 7 is provided comprising a first battery module exhaust 18, a second battery module exhaust 19 and a first battery manifold 20 arranged to connect the first and second battery module exhausts to a first flow path extending to an exhaust port 8 of the aircraft. The first battery manifold 20 includes a first valve 28 comprising a first flap 29 having a first position in which fluid flow from one of the first and second battery module exhausts is restricted; a second position in which fluid flow from the other of the first and second battery module exhausts is restricted; and a neutral position in which fluid can flow from both first and second battery module exhausts to the first flow path. The first valve 28 is biassed towards the neutral position. The venting system of the present invention is more lightweight than was hitherto achievable, protects other modules and components of the energy storage system from the heat of gas emissions and reduces pressure losses, so that the emitted gas is more likely to exit the aircraft, typically via a burst disc
