Investigation Of Mk 25 Mod 2 Smoke Flare Composition

A study is made on various chemical and physical characteristics of the Mk 25 Smoke-Flare Composi tion, which is basically a red phosphorus-magne sium-manganese dioxide system. A scheme for chemical analysis is reviewed. Physical phase changes and chemical reaction mechanisms of the components and of the mixture as a whole are ex plored by differential thermal analysis and ther mogravimetric analysis. Factors affecting the ignition point are considered. After some inves tigation, an attempt is made to write the prin cipal internal and external reactions for this complex and non-stoichiometric system. Behavior characteristics, such as sensitivity, stability, heat of reaction, ignition point, etc., are determined and reported. (Author).

A study is made on various chemical and physical characteristics of the Mk 25 Mod 2 Starter Composition, which is an oxygen deficient siliconlead dioxide - cupric oxide system. A scheme for chemical analysis, already provided in RDTR No. 27, is reviewed. Physical phase changes and chemical reaction mechanism of the compvents, and of the mixture as a whole are explored by differential thermal analysis and thermogravimetric analysis. The principal chemical reactions are considered and the theorectical thermodynamic values compared with experimental values. Behavior characeristics, such as sensititity, stability, heat of reaction, ignition point, and other available information are included in a Pyrotechnic Data Collection Sheet. (Author).

Training Circular (TC) 3-09.81, "Field Artillery Manual Cannon Gunnery," sets forth the doctrine pertaining to the employment of artillery fires. It explains all aspects of the manual cannon gunnery problem and presents a practical application of the science of ballistics. It includes step-by-step instructions for manually solving the gunnery problem which can be applied within the framework of decisive action or unified land operations. It is applicable to any Army personnel at the battalion or battery responsible to delivered field artillery fires. The principal audience for ATP 3-09.42 is all members of the Profession of Arms. This includes field artillery Soldiers and combined arms chain of command field and company grade officers, middle-grade and senior noncommissioned officers (NCO), and battalion and squadron command groups and staffs. This manual also provides guidance for division and corps leaders and staffs in training for and employment of the BCT in decisive action. This publication may also be used by other Army organizations to assist in their planning for support of battalions. This manual builds on the collective knowledge and experience gained through recent operations, numerous exercises, and the deliberate process of informed reasoning. It is rooted in time-tested principles and fundamentals, while accommodating new technologies and diverse threats to national security.
