摘要： PROBLEM TO BE SOLVED: To provide a tilt rotor down stop assembly for separating a horizontal load and having a low height by providing a pivotally movable striker assembly and a down stop assembly including a cradle assembly formed so as to receive the striker assembly freely to be removed. SOLUTION: A striker assembly 31 includes a base member 33 formed so as to receive an adjustable striker arm 35 formed with angle. The base member 33 includes an installation opening part 36. The striker arm 35 is formed into an L-shape having a post part 37 and a leg part 39. A down stop assembly is moved from a tip part 49 to a leg part 39 of the post part 37 generated by a tilt rotor assembly in the flying mode by the striker assembly 31. With this structure, a cradle assembly can be maintained at a low height.

摘要： PROBLEM TO BE SOLVED: To deflect the exhaust gas stream of an aircraft engine from an aircraft's fuselage structure.
SOLUTION: Nozzles (3, 5) for discharging high velocity air are positioned on each side of an exit of an aircraft engine duct (1) exit. High velocity air is discharged tangential to an outer surface of each nozzle (3, 5) and follows the contour thereof. Each nozzle (3, 5) is positioned so that when the high velocity air separates from the outer surface of the respective nozzles (3, 5), it flows outwardly relative to the aircraft's fuselage structure. The high velocity air from the nozzle (3) closest to the aircraft's fuselage structure impinges on the exhaust gas stream (35, 57), deflecting the stream in a direction (43) away from the fuselage. The high velocity air from the nozzle (5) furthest from the fuselage creates a low pressure area which deflects the exhaust gas stream (35, 37) away from the fuselage. In combination, the two nozzles (3, 5) deflect the exhaust gas stream (35, 37) away from the fuselage to some extent.

摘要翻译：要解决的问题：使飞机发动机的废气流从飞行器的机身结构偏转。
解决方案：用于排出高速空气的喷嘴（3,5）位于飞机发动机导管（1）出口的出口的每一侧。高速空气与每个喷嘴（3,5）的外表面相切地排出并且遵循其轮廓。每个喷嘴（3,5）被定位成使得当高速空气与相应喷嘴（3,5）的外表面分离时，其相对于飞行器的机身结构向外流动。来自最靠近飞机机身结构的喷嘴（3）的高速空气撞击排气流（35,57），使流沿机身偏离方向（43）偏转。距离机身最远的喷嘴（5）的高速空气产生使排气流（35,37）远离机身偏转的低压区域。两个喷嘴（3,5）组合地使排气流（35,37）偏离机身一定程度。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a vibration absorbing device with which the weight compensates the vibration effectively in all five directions, i.e., ahead and aside in the plane, vertically, and in the pitching and rolling directions. SOLUTION: This vibration absorbing device concerned 20 is equipped with a mass member borne in the stationary state by intra-plane springs 36 at a certain spacing from a base plate 22, top plate, and spring holding structure 45. The mass member has a buffer surface contacting with a motion restrictor 30 for the base plate. The mass member, base plate, and top plate can be equipped with a passage 24 passing the axis 26. Adjustment of this vibration absorbing device can be made by varying the intra-plane spring (s), the degree of preliminary compression, and the size of the mass achieved through addition or removal of a mass adjusting weight.
