TL;DR: This paper discusses the application of an integrated approach for project modeling and proposes a new graphic tool called PACT for evaluation of project status that was used successfully with multiple advanced technology projects within the Indian Guided Missiles Development Programme.
Abstract: Project Management Systems can use a variety of tools to model and visualise project status. This paper discusses the application of an integrated approach for project modeling and proposes a new graphic tool called PACT for evaluation of project status. An integrated performance monitoring system comprising many tools, including PACT, was used successfully with multiple advanced technology projects within the Indian Guided Missiles Development Programme. The approach provided a better insight into the status and problems of projects, and enabled management to initiate the most appropriate actions towards better performance.

TL;DR: In this paper, the requirements and challenge areas of research, and calls for consortium approach involving academic institutions are discussed, where high purity electronic materials like silicon, indium, phosphorus, Cu clad materials, photo resists and epoxies are very important for the programme.
Abstract: Missile Development Programme has provided focal thrust to indigenous materials and components. Materials have been selected on the basis of their high strength to weight ratio, good corrosion resistance, high fracture toughness, easy fabricability and reliable quality. Alloys of magnesium, aluminium, titanium and maraging steel are extensively used for airframe and propulsion systems. Polymer materials and carbon-carbon composites are major nonmetallic materials. Development of high purity electronic materials like silicon, indium, phosphorus, Cu clad materials, photo resists and epoxies are very important for the programme. The paper covers the requirements and challenge areas of research, and calls for consortium approach involving academic institutions. R and D laboratories and industries to ensure self reliance.

TL;DR: In this article, it was shown that none of the mass-flow-rate terms should be present in the equations of motion because the force and moment attributable to engine thrust are considered as external forces and moment acting on the vehicle.
Abstract: Introduction B ILIMORIA and Schmidt give an integrated development of equations of motion for simulating the trajectory of a vehicle incorporating structural elastic modes, effect of rotating parts, and mass flow rates of air-breathing engines in the equations of motion. This Note shows that the terms containing mass flow rates in the equations of motion of Ref. 1 are erroneous. Further, it is shown that none of the mass-flow-rate terms should be present in the equations of motion because the force and moment attributable to engine thrust are considered as external force and moment acting on the vehicle.
