PROBLEM TO BE SOLVED: To provide housing type aircraft engine run-up equipment capable of backwardly changing the direction of an air flow introduced downward from a roof side suction port of a front end part of a hanger, capable of sufficiently straightening an introduced air flow, and capable of eliminating an exhaust duct. SOLUTION: This aircraft engine run-up equipment 1 has the hanger 4 for forming a test room 3 capable of housing an aircraft 2, the air introducing suction port 6, and an air exhausting exhaust passage 7. The suction port 6 is arranged on the upper roof side of the front end part of the hanger 4. An exhaust passage 7 communicating with the rear end of the test room 3, and extending backward and upward from this rear end is arranged in a rear end side part of the hanger 4. One or plural air flow direction changing members 20 are arranged in the lower side vicinity of the suction port 6 for guiding the air flow introduced from the suction port 6 toward the aircraft 2 housed in the hanger 4. A straightening mechanism 18, a first straightening member 21, a straightening space 19, a second straightening member 22, a third straightening member 23, and a fourth straightening member 24 are arranged in the suction port 6 or the vicinity.
