  1. Development of a Multidisciplinary Curriculum for Intelligent Systems (MCIS) Dimitris C. Lagoudas Jeffery E. Froyd Othon K. Rediniotis Thomas W. Strganac John L. Valasek John D. Whitcomb Rita M. Caso http://smart.tamu.edu/CRCD

  2. Goals of MCIS Effort at TAMU • Develop new curriculum track on Intelligent Systems emphasizing aerospace technologies. • Increase knowledge and interest in using smart materials to design intelligent systems. • Include a 2 semester design course and a one-on-one directed studies course with a faculty member. • Offer an “Intelligent Systems Track” Certificate. • 15 hour program • Includes recognition on transcript URICA and design team Synthetic Jet Actuator

  3. Courses Impacted • AERO 101 – Introduction to Aerospace Engineering (F01) • ENGR 111/112 – Foundations of Engineering I/II (F01/S02) • ENGR 211/213/214 –Basic engineering science courses (S02, F02) • AERO 302 – Aerospace Engineering Laboratory I (S02) • AERO 304/306 – Structural Mechanics I/II (F01, F02) • AERO 401/402 – Senior design sequence (F03, S04) • AERO 405 – Aerospace Structural Design (F01) • AERO 489* – Special Topic: MEMS for Aerospace Engineering (F01) • AERO 489* – Special Topic: Aerospace Intelligent Systems (S02) *New Course

  4. Foundations of Engineering (ENGR 111/112) Activities with Shape Memory Alloys (SMA) Butterfly Demonstration:SMA Linear Actuator Heat Engine Demo:SMA Efficiency/Thermodynamics Thermobile™ Demo:SMA Properties/Thermodynamics Stiquito Project:Application of SMA

  5. ENGR 111 Project Walking Robot • Robot (Stiquito) specifications: • Must be actuated by SMAs • Goal is maximum distance in 3 minutes • Only contact can come from ground • Must be an autonomous system • Assigned to 24 four-person student teams in ENGR 111 • Maximum distance traveled was 48cm.

  6. Piezo patch Shaker ENGR 11x/21x DemonstrationPiezoelectric Beam Demo • Demonstration for Freshman/Sophomore to show the basic function of a piezoelectric patch Planned Setup • Piezoelectric patches will be used to cancel a known vibration. Beams with patches and amplifier

  7. ENGR 111/112Integrated with AERO 401/402 • There are two primary objectives: • Let first year students gain practical experience working on the design and construction of an aerospace vehicle while working with upperclassmen. • Allow seniors to learn and develop important project management skills needed in the workplace today.

  8. Without Actuation With Actuation AERO 302 Project Synthetic Jet Actuators Introduction into the classroom: AERO 302 (Aerospace Engineering Laboratory 1) Use of Hot-Wires and Fast- Response Pressure Probes to measure actuator exit velocity as a function of operating frequency Visualization of the effect of Synthetic Jet Actuators on airflow
