Assignment Number 1

1. Analyze drag reduction strategies used in modern commercial aircraft like the Boeing 787; recommend improvements using NACA airfoils and composite materials. 2. Compare piston, turbofan, and rocket propulsion systems in current industry applications; evaluate thrust equations for a satellite launch mission. 3. Investigate failure cases in aircraft fuselage structures; propose material selection for enhanced fatigue resistance in commercial jets.

Case Study Assignment

1. Airbus transitioned from conventional aluminum aircraft to advanced composite-based designs in modern aircraft like the A350. Analyze how historical developments in aerodynamics, materials, and propulsion influenced modern aircraft design evolution from early monoplanes to present-day commercial jets. 2. Modern fighter aircraft employ composite materials to enhance the strength-to-weight ratio and stealth performance. Compare monocoque and semi-monocoque construction methods and justify material selection for high-performance military aircraft. 3. ISRO launch vehicles rely on different rocket propulsion systems. Explain the thrust equation and compare solid and liquid rockets in terms of operational flexibility, reliability, and mission requirements.
