PATTERNS OF USE OF AEROSPACE ENGINEERING E-TECHNICAL REPORTS BY THE INDIAN AEROSPACE SCIENTISTS AND ENGINEERS IN BANGALORE: A RESEARCH SURVEY

摘要

A large number of aerospace e-technical reports are frequently referred by the aerospace scientists and engineers for their day to day research work. A survey study was undertaken to ascertain the most frequently used aerospace e-technical reports amongst 16 selected aero- space organizations of Bangalore. The study is restricted to geographic boundary of the city of Bangalore. Out of the 650 survey questionnaires distributed to the scientists and engineers, a total number of 612 were received back and finally 583 responses found suitable were selected for the study. The total responses usable from all the 16 aerospace organizations amounted to 89.7 percent. The analysis is based purely on the responses received from the aerospace scientists and engineers representing these selected aerospace organizations. The responses from the participants towards the extent of use of the e-technical reports were graded on a scale of 4 to 0, 4 representing to a great extent. The major findings that the authors would like to report in this paper are: The most frequently referred aerospace engineering e-technical reports by these scientists and engineers are: (a) 'USA, NASA', followed by, (b) 'USA, AIAA', (c) 'Indian NAL', (d) 'AGARD', (e) 'British ARC and RAE', (f) 'ESA', (g) 'French ONERA', (h) 'German DFVLR, DLR and MBB', (i) 'Dutch NLR', (j) 'Russian TaAGI', and, finally, (k) 'Japanese NAL'. Analysis of Variance (ANOVA) was applied for testing the significant difference among the mean scores attained from 16 aerospace organizations towards the 'Use of e-Technical Reports'. It is observed that all the 16 aerospace organizations show a significant difference (P < 0.05) in their mean scores viz., 'AGARD', 'British ARC and RAE', 'ESA', Indian NAL', 'German DFVLR', DLR and MBB', 'Japanese NAL', 'Russian TaAGI', 'Dutch NLR', 'USA, NASA' and 'USA, AIAA', except for 'French ONERA' (P = 0.092).
