The invention relates to the technical field of aircraft trial, and provides a universal test flight platform of a turboshaft engine, which comprises an aircraft, a first test cabin, a first power pack, an independent reduction gearbox and a propeller, two wings are respectively arranged on two sides of the aircraft, the first test cabin is arranged on one wing, the first test cabin and the first power pack are positioned on the same side of the aircraft, and the independent reduction gearbox is arranged on the first test cabin. The first power pack is arranged at the joint of a wing and the aircraft, the first test chamber is provided with a containing cavity, a mounting part is arranged in the containing cavity and used for mounting an engine and enabling the axial direction of the engine to be consistent with that of the containing cavity, the engine is connected with the first power pack through the first test chamber, and the independent reduction gearbox is arranged in the containing cavity. The propeller is arranged outside the containing cavity and located at the end of the first test chamber, and the engine is in transmission connection with the independent reduction gearbox and the propeller in sequence. The turboshaft engine is well matched with the test flight platform, test flight verification of the whole flight envelope of the turboshaft engine is met, and the test flight platform has the characteristic of universality.
