Unformatted text preview: radius (ft) velocity (ft/sec) Maximum turn rate: The thrust limited maximum turnrate velocity is 194 ft/sec., as computed in the author’s solution. This point (denoted by point D in Figure 6.2) lies to the right of the intersection point A, and is on the thrustlimit curve. To observe that the best turnrate velocity, generate plot for the turn rate, using equations 6.18 and 6.11. This is given below. 150 160 170 180 190 200 210 220 230 240 250 0.2 0.25 0.3 0.35 0.4 0.45 0.5 turnrate .vs. velocity turnrate (rad/sec) velocity (ft/sec) stall thrust The maximum turnrate at any given velocity is the minimum of the two curves, implying that for velocities above the interection point A, the max. turnrate is determined by the thrustlimit. The maximum of the thrust limit curve lies at the computed velocity of 194 ft/sec . And hence the maximum turnrate is 0.331 rad/sec ....
