Aircraft are launched from aircraft carriers using jet blast deflectors, which deflect the jet blast upwards and over the flight deck to protect the ship, other planesequipment, and personnel. In jet blast deflection there is a need for alternative approaches that includes a stronger, light-weight structure that can be easily maintained while not disrupting existing launch and aircraft recovery operations. This invention addresses these needs by providing superior load bearing capabilties in addition to significant weight reduction. The invention also uses passive cooling concepts to more efficiently achieve heat dissipation from the jet blast deflector.
