What is the purpose of the aircraft fuselage?
fuselage, central portion of the body of an airplane, designed to accommodate the crew, passengers, and cargo. It varies greatly in design and size according to the function of the aircraft.
What is the purpose of a longeron and Stringer in a semi-monocoque type fuselage?
The fuselage is a semi-monocoque structure made up of skin to carry cabin pressure (tension) and shear loads, longitudinal stringers or longerons to carry the longitudinal tension and compression loads, circumferential frames to maintain the fuselage shape and redistribute loads into the skin, and bulkheads to carry …
What are the aircraft design constraints?
For most aircraft projects there are several constraints related to field performance (e.g. take-off, climb, balanced field length, stall speed, landing characteristics) and several linked to other mission segments (e.g. minimum cruise speed, climb rates/times, turn rates, specific excess power, loiter speed, dash …
How does fuselage affect flight?
A supersonic fighter plane has a very slender, streamlined fuselage to reduce the drag associated with high speed flight. An airliner has a wider fuselage to carry the maximum number of passengers. The fuselage, along with the passengers and cargo, contribute a significant portion of the weight of an aircraft.
What are the different types of stresses on an aircraft structure?
There are five major stresses [Figure 1] to which all aircraft are subjected:
- Tension.
- Compression.
- Torsion.
- Shear.
- Bending.
What is the advantage of a semi-monocoque fuselage over a monocoque fuselage?
The advantages of the semi-monocoque fuselage are many. The bulkheads, frames, stringers, and longerons facilitate the design and construction of a streamlined fuselage that is both rigid and strong. Spreading loads among these structures and the skin means no single piece is failure critical.
What are the disadvantages of a semi-monocoque aircraft?
Its main disadvantage is that it is somewhat heavy, and it is difficult to make a fiberglass load-carrying structure lighter than a well designed equivalent aluminum structure.
What do aircraft designers do?
Formulate conceptual design of aeronautical or aerospace products or systems to meet customer requirements or conform to environmental regulations. Direct or coordinate activities of engineering or technical personnel involved in designing, fabricating, modifying, or testing of aircraft or aerospace products.
