Flutter induced by aerodynamic interference between wing and tail

B. LASCHKA, O. SENSBURG
1970 Journal of Aircraft  
Vibration Analysis The natural vibration modes, generalized stiffnesses, and masses were determined by calculation and by means of a ground vibration test.  ...  Owing to the upwash, which varies considerably with 2, the aft position of the tail unit is of importance for the magnitude and phase of the wing- induced pressure.  ...

Design of Advanced Titanium Structures

Carlos A. Paez, Robert Gordon
1981 Journal of Aircraft  
The emergence of new titanium fabrication techniques has opened up new possibilities for achieving high structural efficiency at considerably reduced costs.  ...  It can be seen that the reference stress for a design life of 8000 h is almost 40 ksi, and is considerably in excess of the value previously obtained for the larger initial crack that must be assumed at  ...

Enlightened: the art of finger reading*

Björn Breidegard, Yvonne Eriksson, Kerstin Fellenius, Kenneth Holmqvist, Bodil Jönsson, Sven Strömqvist
2008 Studia Linguistica  
This opens up for future Braille education to become more evidence-based and, at the same time, for a new research field: contrastive studies of language in its auditory, visual and tactile manifestations  ...  For some forty years the eye-tracking technology has facilitated the study of eye movement patterns for sighted people during reading and other visual activities.  ...  Further, we expect these studies to lay the foundation of a new generation of tests and diagnostic procedures as well as support tools integrating the online dimension of tactile reading.  ...

Structural Verification of a Fiberglass/Polyimide Acoustic Inlet for the DC-10

William R. Dunbar
1977 Journal of Aircraft  
The general durability and resistance to sonic fatigue were determined by over 250 hr of combined ground and flight testing in front of a CF6 engine.  ...  This assured meeting the design requirements when the core material became available. The fore-and-aft and forward edge closeouts were tapered to flanges parallel to the wetted surface.  ...

D. M. RAO
1983 Journal of Aircraft  
In addition, location of the flap hinge aft of and underneath the wing leading edge generated substantial thrust from the vortex suction acting on the leading-edge lower surface.  ...  Member AIAA. footprint of the expanding vortex has become too broad, or is beginning to spill over to the wing, and to start a new vortex from that position by means of a new flap surface.  ...

Autogenic feedback training improves pilot performance during emergency flying conditions

M A Kellar, R A Folen, P S Cowings, W B Toscano, G L Hisert
1993 Flight safety digest (Arlington, Va. : 1988)  
In AMB cases, the pilot is in a high state of psychological and physiological arousal and tends to focus on one problem, while ignoring more critical information.  ...  National Aeronautics and Space Administration's (NASA) Ames Research Center, examined the effect of training in physiological self-recognition and regulation, as a means of improving crew cockpit performance  ...  This definition and the figures cited above can be misleading, however, as a result of the simplistic approach generally taken in the identification of human error as contributory or causal in aircraft  ...
