AERODYNAMIC CHARACTERISATION OF RLV-TD
NAL trisonic wind tunnel facility is being used extensively to characterize the aerodynamics of Reusable Launch Vehicle Technology Demonstrator (RLV-TD) configuration during various phases of flights as well as to generate very important data viz. FADS calibration coefficients, hinge moments, unsteady aerodynamics, flow visualization and dynamic derivatives of RLV-TD HEX-1 mission, which is planned in the middle of next year. The descent phase aerodynamic characterization (TDV alone) was completed and the huge data generated was of immense use for the design and simulations. The aerodynamic community has lauded the voluminous data, which runs into 1196 tables that was followed for the first time, as practiced in aircraft industry.
In order to meet RLV-HEX-1 mission target of May-June 2009, the complete aerodynamic characterization during ascent phase as well as FADS calibration data were essential by November, 2008. On the request from ISRO, the test program was undertaken on priority by the NTAF team. Also during the course of the tests, the test data were made available in real time to the Project and design teams that facilitated making a first cut assessment on the result and to carry forward the remaining program. The total number of blowdowns was more than 450 and the whole test program went smooth. The NTAF team rose to meet the crises, like power problems and put extra effort in order to ensure timely completion of the program.
On behalf of the project, Dr K Sivan Project Director, RLV-TD, VSSC has appreciated the NTAF team for putting their best efforts to complete the RLV-TD ascent phase aerodynamic characterization and FADS calibration test for providing the data within the targeted schedules . Dr K Sivan has also mentioned that he is looking forward to the continued support and cooperation from NAL for the further test programs.
