Title: Fuel Control Testing Device
Inventor: KARLIN WILLIAM FRANCIS
IPC: G01M13/00
Filed: 1968-03-25
Abstract: 1,182,064. Monitoring performance of an engine fuel supply electrically. UNITED AIRCRAFT CORP. March 25, 1968, No. 14309/68. Heading G1N . The performance of a gas turbine engine fuel control is monitored in situ by sensing various operating parameters, e.g. the speed of rotation of the compressor (N), the mass flow-rate of the fuel (Wf), the combusion chamber or burner pressure (Pb) and plotting one against another, or against a combination of two, or against time. Differences between the actual and theoretical plots indicate faulty operation of the control. As shown, signals representing N, Wf and PB are derived, e.g. from the tachometer 22, Fig. 2, of the aircraft engine, a turbine wheel flow sensor 26 and a variable reluctance, or strain gauge type device 30 in the combustion chamber respectively and are individually supplied, after conversion to D.C. where necessary, to a mode selector switch 48, together with a D. C. signal representative of Wf/Pb from divider 50. Output lines 54, 56 of the switch are connected to the X, Y co-ordinates controls of a recorder 64, the switch being so connected that signals representative of Pb, Wf or Wf/ Pb together with N may be connected to its output lines 54, 56 or signals representative of Pb, Wf or N may be connected to line 54, with nothing on line 56. Thus, in the former mode a plot of Pb, Wf or Wf/Pb against N is obtained and in the latter mode a plot of Pb, Wf or N against time is obtained. In plotting Wf/Pb against N, Fig. 4 (not shown) in order to be able to dwell on the acceleration or deceleration schedule of the control, a false burner pressure signal is generated by connecting a regulatable pressure supply (74, 76, Fig. 3, not shown), to the fuel control in place of the pressure signal from the pressure sensor in the engine burner. Thus the fuel supply is controlled in accordance with the pressure of the supply (74, 76). The performance of the engine may be checked for cycling of the power lever, bleed valves, exhaust nozzle area and the false burner pressure.
