Perception is Everything: Repairing the Image of American Drone Warfare

This thesis will trace the United States’ development of unmanned warfare from its initial use in the World Wars through the Cold War to its final maturation in the War on Terror. The examination will provide a summary of unmanned warfare’s history, its gradual adoption, and concerns regarding the proliferation of drones use to understand the emphasis on unmanned weapons in the American Military. In each phase of development, a single program will be focused on to highlight special areas of interest in the modern day. Finally, the modern era of unmanned systems will focus on the growing integration of new weapon systems which no longer fulfill niche roles in the armory but act as fully vetted frontline combatants. Brought together, this examination will show drones have earned their place as integral tools in the American military inventory as faithful defenders of democracy

US and USSR Military Aircraft and Missile Aerodynamics 1970-1980. A selected, annotated bibliography, volume 1

The purpose of this selected bibliography (281 citations) is to list available, unclassified, unlimited publications which provide aerodynamic data on major aircraft and missiles currently used by the military forces of the United States of America and the Union of Soviet Socialist Republics. Technical disciplines surveyed include aerodynamic performance, static and dynamic stability, stall-spin, flutter, buffet, inlets nozzles, flap performance, and flying qualities. Concentration is on specific aircraft including fighters, bombers, helicopters, missiles, and some work on transports, which are or could be used for military purposes. The bibliography is limited to material published from 1970 to 1980. The publications herein illustrate many of the types of aerodynamic data obtained in the course of aircraft development programs and may therefore provide some guidance in identifying problems to be expected in the conduct of such work. As such, this information may be useful in planning future research programs

Screening and Evaluation of Operational Effectiveness Indicators for Air Defense Missiles Based on Improved PCA

With the significant role played by air defense missile weapon systems in various local wars and armed conflicts, the significance of operational effectiveness evaluation has become increasingly important. This article determines the operational efficiency index system model of the air defense missile weapon system by constructing the operational environment of the air defense missile weapon system. The improved principal component analysis(PCA) method and MATLAB programming are applied to reduce the dimensionality and decorrelation of the operational performance indicators of the air defense missile weapon system’s operational environment, and the optimized indi_x005fcator system model of the operational efficiency indicators of the air defense missile weapon system is output. At the same time, the weight value is also closer to the actual combat situation, to achieve an accurate and express evaluation of combat effectiveness. By analyzing a case of evaluating the operational effectiveness of a certain type of air defense missile weapon system, key indicators were selected, and the effectiveness of the model in screening the operational effectiveness evaluation indicators of air defense missile weapon systems was verified. This provides a basis or reference for the subsequent optimization of air defense missile weapon system schemes and the evaluation of operational effectiveness and has certain promoting significance

Decision Aids for Airborne Intercept Operations in Advanced Aircrafts

A tactical decision aid (TDA) for the F-14 aircrew, i.e., the naval flight officer and pilot, in conducting a multitarget attack during the performance of a Combat Air Patrol (CAP) role is presented. The TDA employs hierarchical multiattribute utility models for characterizing mission objectives in operationally measurable terms, rule based AI-models for tactical posture selection, and fast time simulation for maneuver consequence prediction. The TDA makes aspect maneuver recommendations, selects and displays the optimum mission posture, evaluates attackable and potentially attackable subsets, and recommends the 'best' attackable subset along with the required course perturbation

MODELING ENERGY STORAGE REQUIREMENTS FOR HIGH-ENERGY LASERS ON NAVY SHIPS

The Navy requires a weapon system that effectively counters swarms of unmanned aerial vehicles (UAVs), anti-ship cruise missiles (ASCMs) and small boats to improve the ship’s self-defense capability. The Navy is studying the efficacy of laser weapon systems against these threat classes as a complement to existing kinetic weapons. While laser weapon systems provide several benefits to Navy ships, they are susceptible to environmental effects and have greater power requirements than available. Therefore, it is necessary to assess energy storage systems to meet these power requirements. This study determined the size of the energy storage system to defeat enemy swarms that threaten the safety of U.S. Navy ships. The study utilized Atmospheric Naval Postgraduate School Code for High Energy Laser Optical Propagation (ANCHOR) and a discrete event model to analytically determine the dwell time a laser weapon system requires for hard kills on ASCM, UAV and fast attack craft/fast inshore attack craft (FAC/FIAC) threats in a variety of operational conditions. This research varied the types of threats and the environmental effects of visibility and air/sea temperature to determine their impact on laser performance. Finally, this study conducted a brief comparison of three different types of energy storage systems that support the results of the model.CNSP/Lhttp://archive.org/details/modelingenergyst1094559554Lieutenant, United States NavyApproved for public release; distribution is unlimited

Supersonic through-flow fan assessment

A study was conducted to assess the performance potential of a supersonic through-flow fan engine for supersonic cruise aircraft. It included a mean-line analysis of fans designed to operate with in-flow velocities ranging from subsonic to high supersonic speeds. The fan performance generated was used to estimate the performance of supersonic fan engines designed for four applications: a Mach 2.3 supersonic transport, a Mach 2.5 fighter, a Mach 3.5 cruise missile, and a Mach 5.0 cruise vehicle. For each application an engine was conceptualized, fan performance and engine performance calculated, weight estimates made, engine installed in a hypothetical vehicle, and mission analysis was conducted
