| 内容記述 | It is ascertained that reachable or controllable points of a dynamic system in which a system equation is linear with respect to control variables can be obtained even for cases with first-order state-inequality-constraint by using an effective optimizing method based on linear programming. With this method, controllable height regions of aircraft of aircraft for spot landing are investigated. The effect of flight parameters such as approach path angle and velocity and the effects of the constraint quantities of elevator angle, angle of attack and pitch attitude on the controllable region are made clear for a middle size turbo-prop transport aircraft. The widest controllable height region of the model aircraft at 1/3 naut mile point from landing spot is obtained at the approach velocity of 1.125∿1.175V_s irrespective of approach angle. A safety margin factor which is the ratio of maximum allowable steady flight length to the total approach and landing flight length in statistical meanings is introduced and effects of the approach speeds and angles to this factor are discussed. It may be concluded that the slope of the glide path of the conventional aircraft (-2.5∿-3.0deg.) in ILS is reasonable in view of safety and that, if selected carefully, the location of this glide path to an objective touch down point can be held to the specified point without any adjustment due to the degree of skillfulness of the pilot. This adjustment seems to be required for more shallow approach path angle. | |||||||
