Title: Improvements in compressor rear frame
IPC: F01D25/16
Filed: 1958-12-19
Abstract: 856,670. Gas turbine plant. GENERAL ELECTRIC CO. Dec. 19, 1958 [Dec. 26, 1957], No. 41040/58. Class 110 (3). In a compressor rear frame for a gas turbine engine having a thin outer casing which rotatably supports a rotor, at least one load-transmitting strut is provided between the outer casing and an inner casing, the strut being rigidly connected at its inner end to the inner casing so as to move in unison therewith and connected to the outer casing sufficiently remote from the rigid flanges of the latter to permit substantially unrestrained radial deflection of the outer casing with respect to the inner casing. In the gas turbine engine shown in Fig. 1, a shaft bearing 26 located between compressor 20 and turbine 18 is supported from the inner wall 36 of diffuser passage 37. The radial, axial and torsional loads imposed on the inner wall 36 by the bearing 26 and by the gas forces acting on stator blading 16 are transmitted to the outer wall 32 of the diffuser through radial struts 42, Figs. 1, 2 and 3. Each strut is in two parts, butt-welded together at 48, the radially outer part being a casting or a sheet-metal fabrication. Each strut is attached by fillet welds 64, 66 to the inner wall 36 and to a reinforcing channel 54. Further reinforcement is provided by gussets 73 extending between adjacent channels 54, and gussets 68, 70 extending between each strut 42 and manifolds 56, 58. A flange 45 on each strut 42 is butt-welded to the outer wall 32. Differential thermal expansion of the inner wall 36 and struts 42 with respect to the outer wall 32 is accommodated by radial deflection of the latter, flanges 40, 41 being sufficiently far from the struts 42 to avoid imposing restraint on this deflection. Some of the struts 42 are closed at their inner ends by caps 72, Figs. 2 and 3, so that they can be used as ducts for conveying air bled from the compressor for cabin use or boundary layer control. The bleed air enters the manifolds 56, 58 through openings 74 and then passes by way of openings 76 into the channel 54 and thence through openings 80 into the struts 42. Other struts 42, shown in Fig. 1, are open at their inner ends and are used for the passage of leakage air from a seal 82 to atmosphere.

As shown, switch position 1 corresponds to SQ signals LT, RT which are reference phase shifted 13, 14 and combined 26, 27, 28 to form the front signals LF, RF whilst the sum 15 of LT, RT is phase shifted 19 and combined via switch 47 and circuit 38 with the difference output from matrix 27 to form the rear signals LB, RB. These are at -45 degrees relative to an ideal decoder. In switch position 2, corresponding to QS signals LT, RT, the front signals are produced in the same manner except that the difference signal (LT-RT) from matrix 27 is attenuated to 0À4 relative to the sum signal by either an impedance network 34 or an amplifier whose gain is controlled according to matrix type. The rear signals are similarly formed in circuit 38 by combining the difference signal with an attenuated version of the sum signal. The rear signals are + 90 degrees relative to an ideal decoder. In switch position 3, corresponding to BMX signals LT, RT the decoder operates as for position 2 except that jRT is substituted for RT in matrix 27 by means of switch 20. In this case the four outputs are 22À5 and 67À5 degrees relative to those of an ideal decoder. The decoder may be included in a variable mixing coefficient type circuit.
