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. -

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. -

Aerospace technology in its present form has developedalong certain basic principles of aerodynamic forces. Differentparts in an airplane have different functions to balance theaircraft in air, provide a thrust, and control the general mechanisms.Profusely illustrated descriptions provide a picture of whatkinds of aircraft are used for cargo, passenger travel, bombing, and supersonicflights. Propulsion principles and descriptions of differentkinds of engines are quite helpful. At the end of each chapter,new terminology is listed.

Tailored Proprotor Design Common point design between rotors and propellers provides efficient performance for both hover and forward flight. Tailsitter Configuration An X-tail titanium frame ensures structural integrity for bearing landing loads. Modular Payload Bay State-of-the-Art Engines Innovative Hingeless Hub Large compartment and modular Two advanced turboshaft diesel Unique swashplate mounting rack offers flexibility for engines deliver unprecedented method results in compact hub assortment of payload packages. power for exceptional with shorter control rods. performance. Metaltail: Pushing the Envelope High in the montane forests of Ecuador, a steady hum of activity can be heard as Tyrian Metaltail hummingbirds skirt around the flora, pollinating the habitat. Using their high visual acuity, these small creatures can recognize a wide variety of colors and detect the slightest of motions. Coupled with their agile wing movements, they are able to precisely hover in place while in complex and dynamic environments. Inspired by these small but impressive flyers, Metaltail is a fully autonomous, high-speed, reconfigurable aircraft designed by the University of Maryland in response to the 35th Annual AHS Student Design Competition Request for Proposal (RFP) sponsored by the United States Army Research Laboratory (ARL). Developed as a Group 3 Unmanned Aerial Vehicle (UAV), Metaltail is an autonomous coaxial-proprotor swing-wing tailsitter that, like the high-altitude hummingbirds of Ecuador, leverages visual sensory information and adjustable wing geometry to maneuver in megacity environments. -
