PURPOSE: An aircraft engine run-up hangar is provided to secure a building defining a test chamber and having a roof structure with an air inlet, to convert air currents flowing toward an aircraft received in the building, to make exhaust gas directly flow from the test chamber to an exhaust passage, and to produce entrainment to prevent a counter-current of the exhaust gas in the test chamber. CONSTITUTION: An aircraft engine run-up hangar(1) comprises a building(4) defining a test chamber(3) capable of receiving an aircraft; an air inlet structure(6); and an exhaust structure(7). The air inlet structure is formed in a front-end part of a roof structure(14) corresponding to a front-end part of the building. The exhaust structure is connected to a rear end part of the building and the exhaust structure 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. 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. |
