PROBLEM TO BE SOLVED: To provide a boundary layer controller configured to correspond to the intake side inner peripheral surface shape of a propulsion engine in an aircraft.SOLUTION: The boundary layer controller includes a venturi generator 10 configured such that when a communication path 9 is opened, a partition body 11 in the venturi generator is controlled by a control system to project from a housing part 12 formed into a recessed shape in an intake side inner peripheral surface, an airflow inlet 14 for capturing an airflow flowing in from the intake port front of a propulsion engine is formed toward the intake port front to be opened, a venturi passage 15 for increasing the speed of the airflow captured from the airflow inlet to reduce pressure is formed by a body bottom part 16, inner surfaces of both side parts and the intake side inner peripheral surface behind the airflow inlet, an airflow outlet for outputting the airflow lowered in pressure by increasing the flow speed is formed to be opened in the front of the intake side inner peripheral surface from the opening position of a discharge hole 7, when the communication path 9 is closed, the partition body is controlled by the control system to be housed in the housing part 12, and the bottom outer surface of the partition body and the intake aide inner peripheral surface constitute a continuous curve surface.SELECTED DRAWING: Figure 2

    【課題】航空機における推進機関の吸気側内周面形状に対応することができる境界層制御装置を提供する。【解決手段】連通路9の開時にベンチュリ発生装置10における間仕切り本体11が操縦系統に制御されて吸気側内周面に凹状に設けた収納部12より突出し、推進機関の吸気口前方より流入する空気流を取り込む空気流入口14を吸気口前方に向けて形作って開口し、また、空気流入口の後方に空気流入口より取り込まれた空気流の流速を速めて低圧化を図るベンチュリ通路15を間仕切り本体底部16及び両側面部の各内表面と吸気側内周面とによって形作るとともに、流速を速めて低圧化された空気流が流出する空気流出口を放出孔7の開口位置より吸気側内周面の前方に形作って開口し、連通路9の閉時に間仕切り本体が操縦系統に制御されて収納部12に収納され、間仕切り本体の底部外表面が吸気側内周面と連続曲面を構成するベンチュリ発生装置を備える。【選択図】図2
