INTRODUCTIONThe selection of structural materials to most effectively satisfy newenvironmental requirements and increased design load requirements for advancedA major difficulty thatAir Force weapons systems is of vital importance.design engineers frequently encounter, especially for newly developed materials,materials processing, and product forms, is a lack of sufficient engineeringdata Information to evaluate the relative potential of these developments for aparticular application.The Air Force, in recognition of this need, has sponsored several programs at Battelle's Columbus Laboratories to provide comparative engineeringThe materials included in thesedata for newly developed structural materials.programs were carefully selected to insure that they were either available orcot-id become quickly available upon request and that they would representThe resultspotentially a
developed structural materials of potential interest to the Air Force weapons system, and then to provide "data sheet" type presentations of engineering data for these materials.

The Department of Mechanical, Aerospace and Nuclear Engineering (MANE), is part of Rensselaer's School of Engineering (SOE). MANE offers three collaborative but distinct undergraduate programs leading to a Bachelor of Science degree: Mechanical Engineering (ME), Aerospace Engineering (AE), and Nuclear Engineering (NE).
Established in 1966-1967 as the Department of Aeronautical Engineering, the department was renamed the Department of Aerospace Engineering in 1992. The department runs strong undergraduate and graduate program in Aerospace Engineering and carries ou research in several areas of Aeronautical and Aerospace Sciences.
An Aerospace Engineering aspirant must meet the minimum eligibility criteria to be able to pursue the course. Check the minimum eligibility criteria for Aerospace Engineering below: Minimum eligibility criteria for pursuing Aerospace Engineering is HSc or Class 12 pass with a minimum of 60 percent marks (55 per cent marks for SC/ST) in Science .
