The Saltville thrust: investigation of a regional thrust fault in a foreland fold and thrust belt
… are not well understood. The Saltville thrust, a major overthrust in the southern Appalachians, was investigated with respect to deformation mechanics. Thrust termination occurs in the overturned, northwest facing Sinking Creek anticline, at the juncture between the southern and central …

The kanarra fold-thrust system -- The leading edge of the sevier fold-thrust belt, southwest Utah
“The Jurassic to Eocene Sevier fold-thrust belt is the subject of continued scientific curiosity in tectonics, stratigraphy, and industry. Understanding its development in southwest Utah is hindered in part due to the multiple origins proposed for the Kanarra anticline, a major leading edge …

Neotectonics Study Along The Frontal Thrust System Of The Fold-Thrust Belt Of Northwest Himalayas, Pakistan
… tectonic deformation of the Himalayan Frontal Thrust System. The first study focuses on the westernmost segment of the Himalayan frontal thrust in the Manzai Ranges. The geologic landscape shows active tectonic features, i.e., stream deflection, wind, and water gaps associated with geologic …

Projectile thrust-drag optimization with external burning
External burning increases base pressure. The characteristic and linearized equations with heat addition are discuss ed, and the condition for maintaining irrotationa ity with heat addition is derived. A transition model, which extends the Crocco-Lees base flow model, and a spin model are …

Compressible Flow Analysis of Thrust Augmenting Ejectors
… need for a method to understand and predict the thrust augmenting characteristics of jet ejectors. The mixing process in ejectors can be analyzed using either the control volume approach, or detailed models based on the Navier -Stokes Equations and the theory of turbulent jets. The control volume …

Aerospike Thrust Vectoring Slot-Type Compound Nozzle
A study of thrust vectoring techniques of annular aerospike nozzles was conducted. Cold-flow blow-down testing along with solid modeling and rapid prototyping technology were used to investigate the effects of slot size, placement, geometry and orientation. The use of slot-type compound nozzles …

Hole-Type Aerospike Compound Nozzle Thrust Vectoring
… study to determine the feasibility of thrust vectoring an aerospike nozzle with the addition of a secondary port. Earlier phases of the study have indicated that a compound aerospike nozzle could provide sufficient thrust vectoring. The addition of a hole-type secondary port was found …

Models of Continental Fold-Thrust Belt Salients
… salients, which form where fold-thrust belts mold to the preexisting irregular shape of the margin; and (4) detachment-controlled salients, which form due to variations in the lateral continuity of weak glide horizons. From this work, it is clear that structural trendline patterns …
