AEROSPACE INDUSTRY R&D (1983-1995)

Aeronautical Engineer/Deputy Manager/Manager, Aerodynamics Group, Hindustan Aeronautics Limited, Bangalore, India (33,000 employee aerospace company)

Worked as ‘core team member’ for design of Light Combat Aircraft (LCA), a supersonic fighter aircraft, currently under production by HAL.

Led a team of 5-7 aeronautical engineers during 1985-1995.

Performed aircraft conceptual design studies, including drag estimation, stability & control derivative prediction, and performance calculation. Defined optimum aerodynamic configuration, including wing and tail shape, size and location.

Analyzed results of over 7000 aerodynamic data polars obtained through low speed and high speed tests of 14 models in 9 wind tunnels (including AEDC, Tullahoma and Calspan, Buffalo). Test results included six-component Force & Moment, control surface hinge moments, wing/fin loads, and surface pressures.

Developed aerodynamic database for LCA in the entire flight envelope for performance prediction and control law design. (Database later verified through LCA flight testing.)

Authored/co-authored 104 technical reports relating to wind tunnel data analysis, configuration definition, and flight aerodynamic database.

Completed advanced management development program (12 weeks full time).

Undergraduate Instruction

1. AE212 Introduction to Aeronautical Design: This course introduces students to concepts of aircraft design, aerodynamics, performance, stability & control, structures, and propulsion. It encourages students to apply their technical knowledge towards engineering design and problem solving. Additional objectives include raising awareness of ethical issues and to encourage self-study for continuing professional education. A ‘glider competition’ at the semester’s end serves as a motivator and ‘reality check’ for students.

2. AE350 Aircraft Structural Analysis: This course provides fundamental knowledge in topics of aircraft structural analysis and design concepts. I employ a consistent elasticity approach, instead of the traditional problem-solving drill, to better prepare the students for current structural design practices based on the finite element methods. The course coverage is tailored for a seamless integration with the next course in aircraft structures (AE 458).

3. AE429 Aircraft Performance and Flight Mechanics: This course introduces the students to the fundamental concepts of airplane aerodynamics, propulsion, and the equations of motion. It enables the students to analytically estimate airplane performance for all phases of flight. I have introduced a semester long project in this course wherein student teams select an airplane and carry out a complete performance analysis. The teams make oral presentations of their work and submit final project reports that enhance the students’ written, oral, and graphical communication skills.

4. AE430 Stability and Control of Aerospace Vehicles: This course provides fundamental concepts of atmospheric flight dynamics and enables students to analytically estimate static and dynamic stability derivatives. It includes the stability of longitudinal and lateral motions using the linearized equations and responses to actuation of open-loop and closed-loop controls. I have introduced project work in this course similar to that discussed above (AE 429). Since AE 429 and AE 430 were given as a single course earlier, I have developed the course material for the two separate courses based on my aircraft design experience.

5. AE458 Design of Aircraft Structures: This course provides knowledge in advanced topics of aircraft structural analysis and design. It introduces the students to finite element analysis and mechanics of composite structures, which are very important for current design of aircraft structures. I relate the material presented in the classroom to real world applications using my industry experience, such as the F-18 structural analysis and optimization. A semester long project using finite element analysis of wing-like structures gives the students an idea about real aircraft structural design.


6. EM 3213 Mechanics of Materials: Learning objectives for this course include understanding of stress and strain, Hooke’s law, and equilibrium equations to calculate the internal forces and moments. Students draw transverse shear and bending moment diagrams for beams under various external loading and support conditions, analyze the response (internal loads, deformation, deflection) of structural members to axial force, transverse shear force, bending moment, and twisting moment. Students analyze statically indeterminate structural members, learn stress transformation, and determine the principal stresses and the maximum shear stress.

Graduate Instruction

1. ME504 Design Methodology: This graduate level course covers fundamentals of engineering design process including design requirements, concept generation and evaluation, product development, modeling and simulation, and robust & quality design. The course is aimed at helping students learn how to be more creative in solving design problems and how to design as part of a group activity.

2. ME657 Selected Topics in Solid Mechanics: This is an advanced independent study course in ‘Smart Structures’ for graduate and undergraduate students. The course material is based mostly on journal papers and my research. This course included introduction to smart materials (piezoelectric and SMA), modeling of smart composite structures (beams and plates), control systems for vibration suppression, and structural health monitoring.

3. EM 6213 Advanced Mechanics of Materials: This course aims to develop understanding of stress and strain, transformation of stress and strain, and stress-strain relationships. Students analyze bending of beams under symmetrical and unsymmetrical loads and determine transverse shear and shear center of thin-walled cross sections. Analysis of torsion of prismatic bars with circular and noncircular sections and elastic stability of columns are included. Students perform structural analysis using energy principles & Castigliano’s theorem and develop understanding of material failure by yielding, fracture, and fatigue.
