Aircraft Systems and Manufacturing
1. Aircraft Systems
Aircraft systems are essential for safe and efficient flight operations. They include:
A. Powerplant System (Engines)
- Provides thrust for propulsion
- Types: Piston engines, turboprops, turbojets, turbofans
- Components: Fuel system, lubrication, ignition, cooling
B. Fuel System
- Stores and delivers fuel to the engines
- Components: Fuel tanks, pumps, filters, control valves
- Ensures proper fuel distribution and balance
C. Electrical System
- Supplies power to avionics, lighting, and essential systems
- Power sources: Batteries, alternators, generators
- Voltage: 14V/28V DC (small aircraft), 115V AC (large aircraft)
D. Hydraulic System
- Powers flight controls, landing gear, brakes, and thrust reversers
- Uses high-pressure fluid for efficiency
E. Pneumatic System
- Used for pressurization, air conditioning, de-icing, and anti-icing
- Uses bleed air from engines or dedicated compressors
F. Flight Control System
- Primary controls: Ailerons, elevators, rudder
- Secondary controls: Flaps, slats, spoilers, trim tabs
- Can be manual, hydraulic, or fly-by-wire
G. Landing Gear System
- Supports the aircraft during takeoff, landing, and taxiing
- Components: Wheels, struts, brakes, retraction mechanisms
H. Ice and Rain Protection System
- Prevents ice buildup on wings, engines, and sensors
- Types: Pneumatic boots, heating elements, chemical anti-ice fluids
I. Pressurization and Environmental Control System
- Maintains cabin pressure and temperature at high altitudes
- Ensures passenger and crew comfort
2. Aircraft Manufacturing
Aircraft manufacturing involves designing, producing, and assembling aircraft and their components.
A. Design and Development
- Begins with conceptual design, aerodynamics, and material selection
- Uses CAD (Computer-Aided Design) and CFD (Computational Fluid Dynamics)
B. Material Selection
- Metals: Aluminum alloys, titanium, steel (used for fuselage, wings)
- Composites: Carbon fiber, fiberglass (used for lightweight, high-strength structures)
C. Manufacturing Processes
- Casting & Forging: Used for engine components, landing gear
- Machining: CNC (Computer Numerical Control) machines for precision parts
- Sheet Metal Fabrication: Used for fuselage and wing panels
- Composites Manufacturing: Layered carbon fiber, resin infusion
- 3D Printing: Used for prototyping and lightweight components
D. Assembly and Integration
- Components (wings, fuselage, tail, engines) are assembled
- Uses automated robotics and manual labor
E. Testing and Quality Control
- Non-Destructive Testing (NDT): Inspects structural integrity
- Flight Testing: Ensures airworthiness and performance compliance
- Certification: Aircraft must meet regulatory standards (FAA, EASA)
F. Supply Chain and Production
- Major manufacturers: Boeing, Airbus, Lockheed Martin, Dassault, Embraer
- Uses a global supply chain for components and materials
