Low Cost Vector Scoring System for Airborne Targets

Whiteman, Don, Bradley, Joe 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / Testing of airborne weapons systems often requires that a scoring system be placed on the target drone to obtain critical miss distance data. Advanced weapons utilizing directional warheads often require a scoring system which yields vector, miss distance and miss direction, information. Scalar scoring systems currently in use are relatively simple and inexpensive. Vector scoring systems are typically complex and the cost of systems which are currently available or are being developed can be prohibitively expensive. Due to the current military budget decline, development of a low cost vector scoring system is desirable This paper introduces a low cost vector scoring system developed for airborne target drones and based on an inexpensive scalar scoring system currently in use. To meet the low cost criteria, vector operation is achieved via minimal modifications to the existing scalar system.

Modelos análiticos para o desenvolvimento de alvos metálicos de alta performance irradiados nos ciclotrons Cyclone 30 e Cyclone 18 do IPEN-CNEN/SP / Analytical models for development of high performance metal targets irradiated in IPEN-CNEN/SP Cyclone 30 and Cyclone 18 cyclotrons

Oliveira, Henrique Barcellos de 16 December 2009 (has links)
Foram desenvolvidos modelos analíticos que descrevem os elementos básicos para irradiações de alvos metálicos em ciclotrons. Parâmetros importantes como valor máximo de corrente de feixe e potência térmica depositada sobre o alvo foram obtidos e confrontados com situações práticas. De forma totalmente inédita, foram determinados analiticamente as características encontradas em situações de intensos transientes térmicos, quando altas concentrações de prótons em uma pequena região do feixe provocam intensos gradientes de temperatura em pequenas regiões do alvo. A comparação dos resultados obtidos com aqueles encontrados na literatura mostraram que os modelos desenvolvidos são satisfatórios, tendo em vista todas as limitações do modelo proposto. / Analytical models were developed that describe the basic elements for metal targets irradiation in cyclotrons. Important parameters such as maximum beam current value and thermal power deposited on target were obtained and compared with practical situations. In an unprecedented way, were determined analytically the features found in intense thermal transient situations, when high protons concentrations in a small region of the beam cause intense temperature gradients in small regions of the target. Comparing with results found in the literature showed that the developed models are satisfactory, in view of all limitations of the proposed model.
