Download or read book Dynamic Stability Derivatives of a Jet Transport Configuration with High Thrust weight Ratio and an Externally Blown Jet Flap written by Sue B. Grafton and published by . This book was released on 1971 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted to determine the dynamic stability derivatives of an externally blown jet-flap transport configuration having clustered inboard pod-mounted engines and full-span triple-slotted flaps. The results showed that the model had positive damping in pitch, roll, and yaw up to the stall angle of attack. The application of power resulted in an increase in pitch damping at high angles of attack and a moderate increase in yaw damping for the higher flap deflections but had no consistent effects on roll damping. For a given level of total engine thrust, the damping derivatives were generally not affected by frequency or by having one engine inoperative.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted to determine the effect of temperature and composition on alloy softening in group VIA metals Cr, Mo, and W alloyed with Re. Results showed that alloy softening was similar in all three alloy systems occurring at homologous temperatures less than 0.16 and at Re concentrations less than 16 atom percent. Rhenium content required to produce a hardness minimum diminished rapidly in all three systems with increasing test temperature. The similarities in hardness behavior in these three alloy systems suggesat common softening mechanism which may arise from lowering the Peierls stress.
Download or read book Fixed base Simulator Study of an Externally Blown Flap STOL Transport Airplane During Approach and Landing written by William D. Grantham and published by . This book was released on 1972 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fixed-base simulator study was conducted to determine the flight characteristics of a representative STOL transport having a high wing and equipped with an external-flow jet flap in combination with four high-bypass-ratio fan-jet engines during the approach and landing. Real-time digital simulation techniques were used. The computer was programed with equations of motion for six degrees of freedom and the aerodynamic inputs were based on measured wind-tunnel data. A visual display of a STOL airport was provided for simulation of the flare and touchdown characteristics. The primary piloting task was an instrument approach to a breakout at a 200-ft ceiling with a visual landing.

Download or read book Simulator Evaluation of the Low speed Flying Qualities of an Experimental STOL Configuration with an Externally Blown Flap Wing Or an Augmentor Wing written by Bruce G. Powers and published by . This book was released on 1973 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The low-speed flying qualities of an experimental STOL configuration were evaluated by using a fixed-base six-degree-of-freedom simulation. The configuration had either an externally blown flap (EBF) wing or an augmentor wing (AW). The AW configuration was investigated with two tails, one sized for the AW configuration and a larger one sized for the EBF configuration. The emphasis of the study was on the 70-knot approach task. The stability and control characteristics were compared with existing criteria. Several control systems were investigated for the normal four-engine condition and for the engine-out transient condition. Minimum control and stall speeds were determined for both the three- and four-engine operation.

This book was released on 1974 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fixed-base simulator program was conducted to define the problems and methods for solution associated with performing decelerating landing approaches on a representative STOL transport having a high wing and equipped with an external-flow jet flap in combination with four high-bypass-ratio fan-jet engines. Real-time digital simulation techniques were used. The computer was programed with equations of motion for six degrees of freedom and the aerodynamic inputs were based on measured wind-tunnel data. The pilot's task was to capture the localizer and the glide slope and to maintain them as closely as possible while decelerating from an initial airspeed of 140 knots to a final airspeed of 75 knots, while under IFR conditions.
