Distributed　electric　propulsion　(DEP)　with　four　propellers　distributed　along　the　rear　edge　of　the　wing　(pusher　DEP　configuration)　promote　aerodynamic　interactions　to　a　higher　level.　To　study　the　aerodynamic　performance　of　DEP　with　the　rear　wing　through　simulations　and　experiments,　the　multi-reference　frame　(MRF)　with　sliding　grid　is　combined　with　wind　tunnel　tests.　The　obtained　results　demonstrate　that　the　lift　and　drag　of　DEP　increase　with　the　angle　of　attack　(AoA)　and　are　related　to　the　relative　position　of　the　propellers　and　wing.　The　propeller　has　no　significant　effect　on　the　lift　of　the　wing,　and　the　lift　and　the　AoA　remain　linear　when　the　AoA　is　less　than　16　degrees.　By　contrast,　the　lift　coefficient　is　much　higher　than　the　baseline　(isolated　wing),　and　the　lift　is　greatly　improved　with　the　increasing　drag　when　the　AoA　is　greater　than　16　degrees.　This　is　because　the　flow　around　the　wing　of　the　pusher　configuration　remains　attached　due　to　the　suction　of　the　inflow　of　the　propeller　on　the　trailing　edge　vortex.　In　addition,　the　acceleration　effect　on　the　free　flow　improves　the　kinetic　energy　of　the　airflow,　which　effectively　delays　the　separation　of　the　airflow　in　the　slipstream　region.
