The invention discloses a distributed electric propulsion propeller slip flow wing lift force measuring device which comprises a base, a free flow power mechanism and a front-back moving mechanism which are arranged on the base, a lifting mechanism arranged on the front-back moving mechanism, a measuring mechanism arranged on the lifting mechanism and an attack angle adjusting mechanism arranged on the measuring mechanism. The attack angle adjusting mechanism is used for fixing a to-be-detected wing; the power output directions of a plurality of free flow propellers of the free flow power mechanism all face the rectifying plate; the front-back moving mechanism is used for adjusting the distance between the wing and the rectifying plate; the lifting mechanism is used for adjusting the placing height of the wings; the measuring mechanism is used for monitoring the stress condition of the wing; the attack angle adjusting mechanism is used for adjusting the placing angle of the wing; compared with a computational fluid mechanics method, the propeller and wing pneumatic coupling test device can more accurately obtain the lift increment of the propeller slip flow to the wing, and compared with a wind tunnel test, the propeller and wing pneumatic coupling test device can quickly obtain a large amount of effective data at low cost.
