This paper presents several derivations of the aiming computing equations for the "Non-Director" or the "Disturbed Reticle" system in the aiming computer systems of the air-to-air gunsight and head-up display weapon. The paper deals with four cases; the fighter attacks the non-maneuverable target which is considered as moving in a straight line at a constant speed; the fighter attacks a maneuvering target and the corrections for the maneuvering of the target are taken into account in the aiming computation; the fighter attacks a maneuvering target and the corrections for the maneuvering of the target and the effect of fighter's own roll rate are taken into account in the aiming computation; during the attack of the fighter on a maneuvering target the historical tracer line (hot line) and a version of the damped tracer line based on multiple Lcos computations are adapted in the computation for air-to-air gun snap-shot.

As a consequence, the compressor may be forced away from its steady operating point and, depending upon its dynamic response, eventually there may be a complete breakdown in the compressor flow, thus leading to surge.

In modern aircraft, airborne weapon launching often causes inlet temperature transients of an axial flow compressor. As a consequence, the compressor may be forced away from its steady operating point and, depending upon its dynamic response, eventually there may be a complete breakdown in the compressor flow, thus leading to surge. This paper presents the authors' research on the unsteady response of the compressor to the temperature transients and the effect of fuel flow reduction on engine stability when there is a sudden increase of engine inlet temperature. In recent years, some attempts have been made to simulate the unsteady response by using a mathematical model. Chamblee [5] presented a model in which the unsteady response is considered with steady state stage characteristics corrected. Das [6] described the unsteady response with a first order delay equation. In order to simulate the unsteady response more reasonably, the authors suggest a second order delay model combined with the "actuator-volume" model [7]. The unsteady response of the compressor to inlet temperature transients is then calculated, using the method of numerical integration. The calculated results are compared with test data and the calculated results supplied by other sources [4,10,11,12]. The comparison proves that the proposed models and calculation method are feasible. To the best of the authors' knowledge, there is no paper published on the effect of fuel flow reduction on engine stability. By way of analyzing the test curves of compressor surge caused by airborne weapon launching, the present paper proposes that the main reason of compressor surge is that the turbine nozzle row may be choked seriously during transient temperature rise at the engine inlet. Because fuel flow reduction can eliminate or reduce the degree of choke, it can play a role in preventing compressor surge. According to the above analyses, simulation calculations are carried out for different combinations of fuel flow reduction and temperature transients, using the second order delay model and the "actuator-volume" model. The calculated results are compared with the test curves from Ref. [1]. It is found the curve tendencies are consistent.
