AU3029 Space Vehicles Syllabus:
AU3029 Space Vehicles Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
The objective of this course is to provide the students to understand the basic space vehicles, manufacturing techniques and to provide the concepts of propulsion, dynamics & controls.
UNIT I UNDERSTANDING FLIGHT – LIGHTER-THAN-AIR & HEAVIER-THAN-AIR
Classification of flight: Lighter-than-air & Heavier-than-air. Historical evolution of Man-made object flight: Balloon & Archimedes principle, Flapping wing & Bird flight, Fixed wing Gliders, Sustained flight with propulsion systems, Rotary-wing & Helicopters. Forces in action during a flight: Lift, Drag, Thrust, weight. Compare: Aerospace vs Space, Levitation vs Controlled-Flight, Propelled flight vsGliding flight, Winged vs Projectile motion, Flapping wing vs Gliding wing
UNIT II MATERIALS, MODELS AND MANUFACTURING TECHNIQUES
Functional requirements: Thermal, Structural, Chemical. Fabrication techniques: Material removal, Material Addition-Additive manufacturing/3D printing, Material forming – Forging, Rolling, Spinning, Extrusion, Material Joining-Welding, Bonding, Bolting.
Material models: Elastic, Plastic, Visco-elastic, Spring-Mass-Damper models, equivalent electrical/mathematical models. Real world material examples: Metallic, Non-metallic-Elastomeric, Composite, Superalloys. Optimization: Strength-to-weight & Stiffness-to-weight ratio.
UNIT III PROPULSION, DYNAMICS & CONTROLS
Principles of achieving controlled flight by various control mechanisms, with simple mathematical models History of Propulsion. Chemical Propulsion: Solid, Liquid, Cryogenic, Hybrid. Electric propulsion.Dynamics of flight in winged and projectile body. Static & Dynamic Stability and Controls
UNIT IV STRUCTURAL DESIGN & PERFORMANCE OPTIMIZATION
Design approach for constraints: Geometry limits – Stiffness based. Material limits – Strength based, Strain based, Fracture-based. Other constraints: Thermal & Thermo-structural. Optimization: Mass, Aerodynamic. Stiffening approaches: Sandwich, Honey-comb, Hat-stiffened, Pressurized. Strengthening: High strength metals, Composites, functionally graded structures.
