Claim:
An apparatus comprising: a propulsion system mount assembly including: a gimbal mount; a plurality of braces directly coupled to the gimbal mount, wherein the braces are attachable to an external portion of an air vehicle; a circular frame; a first set of diametrically opposed brackets on the outer portion of the circular frame; a second set of diametrically opposed brackets on the inner portion of the circular frame, wherein the circular frame is mounted to the gimbal mount at the first set of brackets to rotate approximately 180 degrees; and a truss configured to retain a propulsion system within the circular frame, wherein the truss is rotatably mounted to the second set of brackets and the circular frame has a diameter large enough to allow the propulsion system and truss to rotate approximately 180 degrees through the circular frame, and members on one side of the truss are staggered to extend —further—past—the axis of rotation of the truss than—members on an opposing side of the truss.
