Abstract: 1406826 Airfoil profile NATIONAL AERONAUTICS & SPACE ADMINISTRATION 7 Nov 1972 [9 Nov 1971] 51386/72 Heading B7W [Also in Division F2] An airfoil, designed for operation at subsonic speeds above the critical Mach no. has an upper surface 12 shaped to prevent boundary layer separation by controlling the acceleration of supersonic and subsonic flows; a blunt leading edge 31 rapidly accelerating air to supersonic velocity, a flattened upper portion extending to at least the mid-chord point 28 to maintain this velocity constant until shock wave formation in region 33, a portion 34 maintaining a substantially constant near sonic velocity for a short period aft of the shock wave, and a portion 36 producing a smooth velocity drop to a near free stream value at trailing edge 14. The curvature of the upper surface 12 is at a minimum at a point 22 which is aft of the maximum airfoil thickness t max and forward of the mid-chord point 28, at a distance of about 0À4 of the chord length from the leading edge. The lower surface 13 is shaped to avoid formation of supersonic flow at or below the design Mach no. and has a minimum curvature point 29 about 0À3 of the chord length from the leading edge. Air is accelerated by the leading edge to a high subsonic velocity below the airfoil and this velocity is maintained substantially constant in region 37 before being decreased to a near free-stream value in region 38. A concave cusp portion formed by surface 26 decreases the velocity to values well below the free stream value to improve lifting efficiency. The slope of the upper and lower surfaces 25, 26 near the trailing edge 14 are approximately the same, and the optimum thickness t t,e  of the trailing edge has determined experimentally to be approximately 1% of the chord.

Abstract: 1,263,814. Signal amplitude analyser. WESTERN ELECTRIC CO. Inc. Oct. 27, 1969 [Oct.30, 1968], No.52465/69. Heading G1U. The amplitude of an A. C. signal received from signal oscillator 3 via a transmission path 1-2 under test is monitored by a "window" discriminator 30 which co-operates with bi-stable circuit 40 to produce a signal at a given frequency when the peak amplitude falls between two discriminator limits and zero signal or a higher frequency signal when it occurs respectively below or above the limits. A circuit 51, 52 tuned to the given frequency feeds an indicator circuit comprising transistor 55, relay 60 and indicator 64. The input signal is amplified 10 and applied via a protective circuit including diodes 12, 13 to the discriminator input. Switches 95, 97 select from voltage dividers 89-94 the bias voltages for setting the two limits of the discriminator and this provides an output signal when the input falls between the limits. Thus, it provides two output pulses for each cycle of input signal having a peak above the upper limit, a single pulse for each cycle of input signal having a peak within the limits and no output for a signal having a peak below the lower limit. The discriminator is coupled to a bi-stable circuit which switches when a negative going signal is applied and produces an output equal in frequency to the input signal when the amplitude of the input signal is high, at half the frequency of the signal when its amplitude is within the limits and no signal when its amplitude is low. The indicating circuit is tuned to accept the signals at half the frequency of the input signal. Time varying threshold signals for the discriminator can be provided by sources 102, 104.
