Centre for Aerospace Systems Design & Engineering (CASDE), IIT Bombay

1. Centre for Aerospace Systems Design & Engineering (CASDE), IIT Bombay Presentation to the 3rd Meeting of Joint Policy Committee June 10th 2002

2. Proposal for Continuation of CASDE

3. Future of CASDE? • Success of SE programme depends on the support from Aerospace Organizations. • Modelling & Simulation Lab. has reached a stage where a specific study can be taken up. • MDO framework and studies are still in their preliminary stages, needing further work.

4. Views of Experts • Management Committee • Continuation of SE and Design, Build & Fly Activity • Scientific Programmes Committee • MAV Related Work to be Taken Up • MDO Related Software Tools & Studies to be taken up • MAFV Workshop • Mini Aerial Vehicle Development in 2-3 Years Time • Mr. Prahlada’s (JPC Member) Comments • MDO to be Focal Activity of CASDE, with emphasis on MDO framework to be used by all interested. • MDO Workshop • MDO Framework should be given priority

5. Proposed Plan of Action for the Future of CASDE • Creation of Transition Period Until March 2003. • Completion On-going Tasks • Formulation of Specific Activities in line with the Views of Various Expert Committees, Including the Present JCP Meeting. • Creation of a Work Plan Beyond March 2003. • Support for SE Educational Programme • Specific System Level Activities

6. Plan for Transition Phase • Revision of SE Syllabus to make it Balanced & Suitable for Non-Aero. Fresh Graduates also, in view of 2 year duration and AICTE Guidelines. • Consolidation of Design, Build & Fly Activity, Design Popularization Courses, Completion of Other Labs. as part of the CASDE Infrastructure. • Completion of Preliminary Studies on INS, GPS, Path Planning, Autonomous Navigation.

7. Plan for Transition Phase • MDO Framework Development to Version 2.0. • MDO Studies with NASTRAN & STAR CD • Targeted Studies for Development of Ground Based OILS and AILS, Towards Development of Mini Autonomous Flying Vehicle.

8. Plan for Phase-II • Systems Engineering Education • Revised M. Tech., CEPs, Workshops, . . . • Integrated Modeling & Simulation for System Level Design Studies • Instrumented Flying Platform • Mini Autonomous Flying Vehicle • MDO Framework & Software Tools • MDO Studies • Students’ Creativity Centre

9. Systems Engineering Education • Provision for Non-sponsored SE Students. • Attempt to share special courses with other educational institutions. • More Multi-disciplinary Courses, e.g. Mechatronic Design, to be introduced for a wider audience. • Augmentation of Visiting Faculty Pool from Industry.

10. Integrated Modelling & Simulation for System Level Design Studies • Instrumented Flying Platform. • 3-axis gyros, control surface motion sensors, side slip sensor, sonar for altitude. • Aircraft weight to be kept invariant at 3.5 Kg. • Specified missions to be flown. • Planned to be used as an educational platform for flight mechanics experiments. • Complete digital model for simulation.

11. Integrated Modelling & Simulation for System Level Design Studies • Mini Autonomous Flying Vehicle. • Identification, fabrication of aircraft & aerodynamic characterization. • Identification of sensors/other on-board avionics. • Control law design & implementation • Specific flight missions to be arrived at. • Demonstration of autonomous flying, data acquisition, processing and modifications.

12. Integrated Modelling & Simulation for System Level Design Studies • Student Creativity Centre. • A forum for students to work with aircraft models and get hands-on experience. • A Test Bed for proving new concepts (Discs, Flapping Wings … ). • A facility to introduce students to design principles and Methodologies. • An exercise to inculcate Systems Engg. practices at an early stage.

13. Integrated Modelling & Simulation for System Level Design Studies • MDO Framework Development. • Develop modules for Mission, Controls, Cost, ilities, etc. • Exploring the possibility of wrapping large commercial software within the framework. • Support for exchange of complex data structure & distributed analysis

14. Integrated Modelling & Simulation for System Level Design Studies • MDO Studies. • Aeroelastic optimization with engine model and flight control. • Realistic problem formulation

15. Financial Projections • Financial Support Needed for Phase-II. • Research Scientists, Staff & RAs - 31 • Travel of Invitees/Students/Faculty - 11 • Workstations, Software, Equipment - 23 • Maintenance/Upgradation - 6 • Consumables and Contingencies - 8 • Workshops, Seminars, Short Courses - 6 • A Total of Rs. 85 Lakhs for a 2 Year Period.

16. Financial Projections • Activity wise break-up is as follows. • Office & Educational Programme - 35 • Modelling & Simulation Activities - 25 • MDO Activities - 25 • These are only indicative costs and actual expenditure may depend on emphasis.

17. Head of Account Balance (in Rs.) ASE Information Laboratory Rs. 16, 85, 067 Consumables and Contingencies Rs. 5, 03, 391 Infrastructure Rs. 7, 97, 512 Modelling and Simulation laboratory Rs. 9, 37, 391 Staff Salaries Rs. 7, 10, 893 Renovation & Furnishing Office Space Rs. 2, 81, 011 TA & DA Rs. 7, 89, 802 Workshop Rs. 11, 34, 306 Total Rs. 68, 39, 373 Current Fund Position • CASDE has been careful in spending, particularly for costly items & making use of bulk purchases/educational discounts. • Inadequate faculty/manpower to support many activities.

18. Concluding Remarks • CASDE has been spending at the average rate of around Rs. 35 Lakhs per annum. • It is expected that there will be a balance of around Rs. 30 Lakhs by March 31st, 2003. • Total projected expenditure for continuation of CASDE, for a period of two years beyond March 2003, is Rs. 85 Lakhs.

19. Acknowledgements • CASDE gratefully acknowledges the excellent support that it has been receiving from within IIT & its faculty and from ARDB, along with a host of other aerospace organizations e.g. ADA, CABS, ADE, NAL, DRDL, HAL, ISRO.
