MDO

Combine analysis in several disciplines to optimise

through a formal mathematical process.

www.casde.iitb.ac.in/MDO

MDO - Role of CASDE

• Facilitate creation of– Infrastructure for MDO– Awareness about MDO amongst the industry

• Studies– Optimization and software aspects of MDO

– Issues of integrating

• higher fidelity levels of analysis • formal optimization early in the design phase

MDO - Activities

Awareness Creation

• Formation of SIG-MDO

• SIG-MDO Workshop-cum-Meeting – August 2000. (Continued & active participation by ADA, DRDL, CABS, GTRE)

• Professional Course on MDO – January 2001. Professor Prabhat Hajela, RPI, USA.

Dr. Gary Vanderplaats, GENESIS fame.• Upcoming events

• SIG-MDO Meeting (March 2002)• International Conference on MDO (2003)

MDO - Studies

• Comparative study of various MDO architectures • Response surface approximations; Gradient

Evaluation, Optmisers, . . • MDO studies

– Varying levels of fidelity of analysis

– Simultaneous aerodynamic and structural optimization without/with aeroelasticity

– Wing optimization.; MLC;

– AEW System Optimisation

1. System I/O

2. Decide Subsystems

3. Decide subsystem I/O and interactions

… Down to design tasks

Framework for MDO

• Requirements capture– Through literature

– Study of existing frameworks

(academic pricing for 1 year 4 lakhs to 12 lakhs)

• Sharing models for integration– Make models available

– Retain autonomy
