Abstract
Abstract A portable inflatable shelter (10) for temporarily covering a portion of an object, such as an aircraft engine (12), while partially resting on another portion of the object, such as an aircraft wing (13), includes a plurality of inflatable interconnected tubes (15-25) which carry fabric (26) extending therebetween. When the tubes (15-25) are inflated, the shelter formed thereby includes a roof section over the portion of the object, side sections on each side of the portion of the object, a front access opening, and an overhang section resting on the other portion of the object. The shelter (10) is erected by positioning the uninflated shelter adjacent to the portion of the object to be covered with the front access opening facing the ground. Guy lines (31,33) are then attached from one of the side sections of the shelter to a first point (32) on the ground. Additional guy lines (34,36) are attached from the other side section to a second point (35) on the ground. The shelter (10) is then inflated and pivoted on an axis (30) defined by the first (32) and second (35) points so that the shelfter (10) encloses the portion of the object to be covered.
