What is the main structure or body of a fixed wing aircraft?
The fuselage is the main structure or body of the fixed-wing aircraft. It provides space for cargo, controls, accessories, passengers, and other equipment. In single-engine aircraft, the fuselage houses the powerplant.
How do you design aircraft wings?
Design Process: Wing Design
- Wing area and wing loading.
- Placement of the wing (high, mid or low)
- Wingspan and aspect ratio.
- Planform shape.
- Airfoils.
- Flaps and other high-lift devices.
- Wing twist.
- Wing structural layout.
What are the advantages of fixed-wing aircraft?
Increased range – The main advantage of fixed-wing aircraft is their ability to cover great distances on a single battery. Due to their superior engine efficiency, most commercial models can fly for an hour or more and cover around 400 hectares. This makes them ideal for surveying oil pipelines or electricity pylons.
What will increase the sensitivity to Dutch roll?
Wings placed well above the center of gravity, sweepback (swept wings) and dihedral wings tend to increase the roll restoring force, and therefore increase the Dutch roll tendencies; this is why high-winged aircraft often are slightly anhedral, and transport-category swept-wing aircraft are equipped with yaw dampers.
What is tuck under aircraft?
Mach tuck is an aerodynamic effect whereby the nose of an aircraft tends to pitch downward as the airflow around the wing reaches supersonic speeds. This diving tendency is also known as tuck under. The aircraft will first experience this effect at significantly below Mach 1.
Is the double bubble fuselage worth it?
The double-bubble fuselage will contribute only a little to the overall savings, though. Most will come from the (hypothetical!) engines and the high aspect ratio wings with little sweep. Note that the lower flight speed is compensated by the claim of much shorter boarding times, so the double bubble comes out ahead in block times.
What is a blended wing body (BWB)?
NASA, Airbus, and Lockheed Martin in an attempt to dramatically reduce drag caused by the aircraft and reach the ultra-sustainable status that is required from the ICAO and airlines. Blended wing body (BWB) aircraft is a novel concept which is a combination of a conventional tube and wing aircraft and a flying wing aircraft
What is the BWB configuration of the aircraft?
The BWB configuration is said that the wings, integrated to the larger and wider aerofoil centre body allows the entire aircraft to generate lift and reduce parasite drag, in particular interference drag (Leibeck, 2004; Qin et al., 2004).
What are novel concepts for airplanes?
Novel Concepts are now being analysed by companies such as Boeing, NASA, Airbus, and Lockheed Martin in an attempt to dramatically reduce drag caused by the aircraft and reach the ultra-sustainable status that is required from the ICAO and airlines.
