An aircraft engine run-up hangar comprises a building defining a test chamber capable of receiving an aircraft therein, an air inlet structure, and an exhaust structure. The air inlet structure is formed in a front end part of a roof structure corresponding to a front end part of the building, the exhaust structure is connected to a rear end part of the building and defines an exhaust passage extending obliquely upward from the back end of the building, and one or a plurality of current deflecting members are disposed near a lower end of the air inlet structure to deflect air currents flowing through the air inlet structure into the building toward an aircraft housed in the building. A current-straightening structure is incorporated into the air inlet structure. A current-straightening space is defined under the air inlet structure. A first current-straightening member, a second current-straightening member, a third current-straightening member and a fourth current-straightening member are disposed in a region in and around the current-straightening space.

An aircraft engine run-up hangar comprises a building defining a test chamber capable of receiving an aircraft therein, an air inlet structure, and an exhaust structure. The air inlet structure is formed in a front end part of a roof structure corresponding to a front end part of the building. The exhaust structure is connected to a rear end part of the building and defines an exhaust passage extending obliquely upward from the back end of the building. A ceiling included in the building has an inclined section sloping down backward to straighten air currents, and a groove is formed in a middle part, with respect to width, of the inclined section to permit a vertical tail fin of an aircraft to pass when the aircraft is carried into or out of the test chamber.

Provided are a method for moving a multipurpose field and an apparatus for the same wherein the multipurpose field can be caused to float above a basic floor plate under a fluid pressure and can be moved and placed in a desired position by delivery means. The moving apparatus comprises a nozzle provided over a basic floor plate common to a field region of a roofed stadium and an outdoor region for detecting existence of the multipurpose field and for jetting a fluid upward in response to a detection signal, and delivery means for alternately moving the multipurpose field between both the regions.
