What kinds of loads must aircraft manufacturers consider when designing an aircraft?
The primary factors to consider in aircraft structures are strength, weight, and reliability. These factors determine the requirements to be met by any material used to construct or repair the aircraft. Airframes must be strong and light in weight.
What is used in making aircraft structure?
The metals used in the aircraft manufacturing industry include steel, aluminium, titanium and their alloys. Titanium is also used in the design of aircraft structures as it is a lightweight, strong and corrosion resistant metal.
What is the basic construction of aircraft structures?
The airframe is the basic structure of an aircraft and is designed to withstand all aerodynamic forces, as well as the stresses imposed by the weight of the fuel, crew, and payload. The primary function of an aircraft electrical system is to generate, regulate, and distribute electrical power throughout the aircraft.
How are loads acting on an aircraft structure?
The estimation of loads acting on an aircraft structure is an indispensable task ranging from conceptual, preliminary, and detail design to loads flight testing when an aircraft is already in service. Work package 4 of the DLR project iLOADS covers the range broadly.
Why is load analysis important in aircraft design?
Aircraft loads analysis is an important engineering discipline playing a major role from the first sketch of a new aircraft until the decommissioning. A proper estimation of the loads in the design process is reflected by the structure withstanding the loads and essentially by the structural weight that is about to be minimized.
How are aeroelastic loads used in aircraft design?
To improve the overall aircraft design (OAD) process physics based methods for aeroelastic loads analysis andthe aerodynamic performance assessment of the flexible structure are integrated in an OAD process shown in chapter 2.
