In the present paper, some aerodynamic derivatives corresponding to the angle of attack and the pitching and rolling motions of the arrowhead wings with and without cropped tips (see Fig. 1) in supersonic flow are considered.The wings without cropped tips are first investigated by using the pressure distributions previously determined for the basic delta wings. The results of the aerodynamic derivatives are shown in Figs. 2-4.The, problems of cropped arrowhead wings are solved by the lift cancellation technique which is the same as that of Ref. [5] for the problem of angle of attack, and is extended to the problems of pitch and roll. The basic lift cancellation fields are calculated by the linearized conical flow theory of Ref. [8]. The effects of cropped wing tips are then obtained by appropriate integrations of basic lift cancellation fields. Some numerical results are given in Figs. 7-11.The results hold for wings with supersonic trailing edges for which the Mach lines emanating from the wi. tips may not intersect on the wing.

发送器是气动自动装置中一个很重要部分,但是目前还十分薄弱。因此气动发送器的研究工作在国内外都引起有关方面的极大重视。热偶型温度发送器中,通常在电一气转换部分都用折皺管作为反馈元件,该元件刚度及迟滞较大,这就不得不提高补偿元件中的作用力到数十克以致数百克力。这样在电一气转换器前必须放置前置电子放大器,使结构复杂化。在热偶型温度发送器中引入空气射流力作为补偿力,就根除了上述反馈元件的刚度、迟滞和磨擦的影响,大大提高了补偿系统的灵敏度。这样就有可能直接把通用热电偶的热电势直接转变成气压信号,而不再需要前置电子放大器[1]。本文是作者在刘豹付教授指导下作的研究工作的一部分,旨在实验基础上探索以空气射流力为补偿力的气动热电偶高温发送器的设计与计算方法。
