Advanced Technology Inlet Design, Nra 8-21 Cycle II


Book Description

The report outlines work performed in support of the flowpath development for the DRACO engine program. The design process initiated to develop a hypersonic axisymmetric inlet for a Mach 6 rocket-based combined cycle (RBCC) engine is discussed. Various design parametrics were investigated, including design shock-on-lip Mach number, cone angle, throat Mach number, throat angle. length of distributed compression, and subsonic diffuser contours. Conceptual mechanical designs consistent with installation into the D-21 vehicle were developed. Additionally, program planning for an intensive inlet development program to support a Critical Design Review in three years was performed. This development program included both analytical and experimental elements and support for a flight-capable inlet mechanical design.Sanders, Bobby W. and Weir, Lois J.Marshall Space Flight CenterHYPERSONIC INLETS; DESIGN ANALYSIS; ROCKET-BASED COMBINED-CYCLE ENGINES; ROCKET ENGINE DESIGN; FLOW DISTRIBUTION; THROATS; MACH NUMBER; PROJECT PLANNING; FUNCTIONAL DESIGN SPECIFICATIONS







Intake Aerodynamics


Book Description

"Intake Aerodynamics, Second Edition" presents computational advancements and discoveries in intake aerodynamics. A companion volume to "Practical Intake Aerodynamic Design," this important text considers the problem of airflow, both internal and external to air intake, as applied to civil and military aircraft. It covers the aerodynamics of subsonic and supersonic intakes in real flows, maintaining a progression through the transonic range. Also considered is the joint perspective of the airframe designer and the propulsion specialist in practical cases. Readers will gain insight into the fluid mechanics behind the deceleration of air from free stream to engine velocity, and an understanding of air compression and external drag in extensively revised chapters reflecting progress in the field. More than 300 drawings and diagrams help to illustrate the points defined throughout the book. Copublished with Blackwell Science Ltd.

Rifle Marksmanship


Book Description

All Marines share a common warfighting belief: "Every Marine a rifleman." This simple credo reinforces the belief that all Marines are forged from a common experience, share a common set of values, and are trained as members of an expeditionary force in readiness. As such, there are no "rear area" Marines, and no one is very far from the fighting during expeditionary operations. The Marine rifleman of the next conflict will be as in past conflicts: among the first to confront the enemy and the last to hang his weapon in the rack after the conflict is won. Rifle Marksmanship, a Marine Corps Reference Publication, provides techniques and procedures for Marine Corps rifle marksmanship. Every Marine is first and foremost a rifleman. Rifle Marksmanship reflects this ethos and the Marine Corps' warfighting philosophy. This publication discusses the individual skills required for effective rifle marksmanship and standardizes the techniques and procedures used throughout the Marine Corps. It constitutes the doctrinal basis for all entry-level and sustainment-level rifle marksmanship training.

Experimental Investigation of a Large-scale, Two-dimensional, Mixed-compression Inlet System


Book Description

A large-scale, variable-geometry inlet model with a design Mach number of 3.0 was tested at Mach numbers from 1.55 to 3.2. Variable features of the inlet for off-design operation are an adjustable-height ramp system and a translating cowl. This report presents experimental results for a diffuser and boundary-layer bleed configuration which was optimized at the design Mach number. Overall performance was high with throat-mounted vortex generators, which were effective in reducing flow distortion in the subsonic diffuser at the higher Mach numbers.
