Introduction
The Structures Panel was constituted by the AR&DB in 1971. The panel has been one of the fore runners working towards the overall goals of AR&DB. It has made pioneering efforts in sponsored research and has been responsible for developing R&D culture, which was at infancy in 1960's academic institutions and research laboratories.
In the field of aircraft structures the main thrust in the R&D effort during the past three decades has been on the development of understanding of static and dynamic behavior, in the development of software packages and development and application of testing techniques. An important part of this effort has been oriented towards application to composite structures, a significant development of which has been a state of art computer controlled autoclave facility developed at NAL. Another major area of R&D effort has been fatigue and fracture mechanics of metallic structures, which has finally resulted in the development of full-scale fatigue test facility at NAL for fighter aircraft. Besides this, the other fields, which had received attention, are non-destructive testing, vibrations, stress analysis, aero elasticity, computer aided design, experimental stress analysis, finite element method etc.
Panel Activities
Charters and Composition of the Panel
The Structures Panel was constituted by AR&DB with the following objectives:
- To give technical opinion, recommendations on the feasibility, and financial viability of research and development, of proposals made by research workers in various institutions.
- To suggest of AR&DB work which need to be promoted and indicate and methods of promotion.
Membership of was extended to experts in R&D Organizations, aeronautical industry, IITs, IISc, DGCA and Air HQ. The Panel had held its first meeting on 27th December, 1971 at NAL, Bangalore and had adopted the following guidelines for it's functioning:
- Obtain feedback related to problems encountered on current aircraft in order to enable work to be initiated appropriately.
- Try and obtain state of the art papers relating to aircraft structures from suitable institutions/ individuals.
- Make efforts for compilation of existing literature on various structural aspects and its translation in the form of data usable by designers.
- As far as possible, identify projects with established institution in the interest of building competence for long term work.
- Promote R&D effort through contacts with competent individuals in institution.
