Abstract Flight tests were conducted with two F-111A airplanes to study the effects of steady-state and dynamic pressure phenomena on the propulsion system. Analysis of over 100 engine compressor stalls revealed that the stalls were caused by high levels of instantaneous distortion. In 73 per- cent of these stalls, the instantaneous circumferential distortion parameter, Kg, exhibited a peak just prior to stall higher than any previous peak. The Kg parameter was a better indicator of stall than the distortion factor, K_, and the maximum-minus-minimum distortion parameter, D, was a poor indicator of stall. -
2. Afterburners
2. AFTERBURNERS 2.1 Introduction The simple gas turbine cycle can be designed to have good performance characteristics at a particular operating or design point. However, a particu lar engine does not have the capability of producing a good performance for large ranges of thrust, an inflexibility that can lead to problems when the flight program for a particular vehicle is considered. For example, many airplanes require a larger thrust during takeoff and acceleration than they do at a cruise condition. Thus, if the engine is sized for takeoff and has its design point at this condition, the engine will be too large at cruise. The vehicle performance will be penalized at cruise for the poor off-design point operation of the engine components and for the larger weight of the engine. Similar problems arise when supersonic cruise vehicles are considered. The afterburning gas turbine cycle was an early attempt to avoid some of these problems. Afterburners or augmentation devices were first added to aircraft gas turbine engines to increase their thrust during takeoff or brief periods of acceleration and supersonic flight. The devices make use of the fact that, in a gas turbine engine, the maximum gas temperature at the turbine inlet is limited by structural considerations to values less than half the adiabatic flame temperature at the stoichiometric fuel-air ratio. As a result, the gas leaving the turbine contains most of its original concentration of oxygen. This oxygen can be burned with additional fuel in a secondary combustion chamber located downstream of the turbine where temperature constraints are relaxed. -

Jet engine performance Design Point TS Diagram Typical Temperature vs. Entropy (TS) Diagram for a single spool turbojet. Note that 1 CHU/(lbm K) = 1 Btu/(lb °R) = 1 Btu/(lb °F) = 1 kcal/(kg °C) = 4.184 kJ/(kg·K). Temperature vs. entropy (TS) diagrams (see example RHS) are usually used to illustrate the cycle of gas turbine engines. All the reader really needs to know about entropy is that it represents the degree of disorder of the molecules in the fluid and that it tends to increase! Apart from stations 0 and 8s, stagnation pressure and stagnation temperature are used. Station 0 is ambient. The processes depicted are: Freestream (stations 0 to 1) In the example, the aircraft is stationary, so stations 0 and 1 are coincident. Station 1 is not depicted on the diagram. Intake (stations 1 to 2) In the example, a 100% intake pressure recovery is assumed, so stations 1 and 2 are coincident. 1 Compression (stations 2 to 3) The ideal process would appear vertical on a TS diagram. In the real process there is friction, turbulence and, possibly, shock losses, making the exit temperature, for a given pressure ratio, higher than ideal. The shallower the positive slope on the TS diagram, the less efficient the compression process. Combustion (stations 3 to 4) Heat (usually by burning fuel) is added, raising the temperature of the fluid. There is an associated pressure loss, some of which is unavoidable Turbine (stations 4 to 5) The temperature rise in the compressor dictates that there will be an associated temperature drop across the turbine. -

Gllassman Lewis Research Center Cleveland, Ohio Prepared for the 34th International Gas Turbine Aepengine Congress and Exposition sponsored by the American Society of Mechanical Engineers Toronto, Canada, June 4-8, 1989 ~ .. (NASA-TH-102092) TURBOHACHINERY TECHPCLOGY N89-24320 FOR HIGH-SPEED CIVIL FLIGHT (NBSEL, LEV& Research Center) 26 p CSCL 21E Unclas G3/07 0217641 TURBOMACHINERY TECHNOLOGY FOR HIGH-SPEED CIVIL FLIGHT Neal T. Saunders and Arthur J. Glassman ABSTRACT This presentation highlights some of the recent contributions and future directions of NASA Lewis Research Center's research and technology efforts applicable to turbomachinery for high-speed flight. For a high-speed civil transport application, the potential benefits and cycle requirements for advanced variable cycle engines and the supersonic throughflow fan engine are presented. The supersonic throughf low fan technology program is discussed. Technology efforts in the basic discipline areas addressing the severe operat- ing conditions associated with high-speed flight turbomachinery are reviewed. Included are examples of work in internal fluid mechanics, high-temperature materials, structural analysis, instrumentation and controls. c INTRODUCTION Future Emphasis Shifting to High-speed Flight Two years ago, the aeronautics community commemorated the 50th anniversary of the first successful operation of a turbojet engine. This remarkable feat by Sir Frank Whittle represents the birth of the turbine engine industry, which has greatly refined and improved Whittle's invention into the splendid engines that are flying today. NASA, as did its predecessor NACA, has assisted indus- try in the creation and development of advanced technologies for each new gen- eration of engines. -

The design team lead by Kelly Johnson designed and built the A-12 - a single seat Mach 3+ capable aircraft that was way ahead of its time. The aircraft coupled with the awesome power of twin Pratt & Whitney J-58 Continuous Bleed Afterburning Turbojets was like nothing seen before.

An Online Performance Calculator for Ramjet, Turbojet, Turbofan, and Turboprop Engines
An Online Performance Calculator for Ramjet, Turbojet, Turbofan, and Turboprop Engines Evan P. Warner∗ Virginia Tech, Blacksburg, VA, 24061, USA This paper documents the theory, equations, and assumptions behind an HTML-based online performance calculator for ramjet, turbojet, turbofan, and turboprop engines. Based on inputs of design parameters, flight con- ditions, and engine parameters, the specific thrust (()), thrust specific fuel consumption ()(), propulsive efficiency ([ ?), thermal efficiency ([Cℎ), and overall efficiency ([0) will be output for the engine of interest. Several sample cases are analyzed to verify the functionality of the calculator. These sample cases are derived from engines associated with Virginia Tech, which include: Pratt & Whitney’s PT6A-20 and JT15D-1, Honeywell’s TFE731-2B, and the Rolls Royce Trent 1000. With the help of this calculator, students will now be able to verify their air-breathing jet engine performance value calculations. This calculator is available here. I.
