Aerodynamic and stability analysis of the Safat01 aircraft [PDF]

open access: yesScientific Technical Review, 2015
This paper aimed to predict aerodynamic & stability data for the Safat01 aircraft. Because of its economic and time efficiency, the Digital DATCOM program has been used to predict the stability and control derivatives for the subsonic, low angle of ...

Mechanical Stability of Cylindrical Thin-Shell Wormholes

open access: yes, 2013
In this paper, we apply the cut and paste procedure to charged black string for the construction of thin-shell wormhole. We consider the Darmois-Israel formalism to determine the surface stresses of the shell.

Hydrogen-oxygen proton-exchange membrane fuel cells and electrolyzers [PDF]

open access: yes
Hydrogen-oxygen SPE fuel cells and SPE electrolyzers (products of Hamilton Standard) both use a Proton-Exchange Membrane (PEM) as the sole electrolyte. The SPE cells have demonstrated a ten year life capability under load conditions. Ultimate life of PEM

Lateral ride quality of the B-1 aircraft subjected to a reduction of lateral static stability [PDF]

open access: yes
A method to evaluate the lateral ride quality of a B-1 aircraft subjected to a reduction in lateral static stability is developed. Ride quality is then found for three different relaxed static stability configurations which are augmented by yaw rate ...
