Modern flight vehicles undergo severe conditions such as differences in atmospheric pressure and temperature, or heavy structural load applied upon vehicle components.

Consequently, they are usually the products of various technologies including aerodynamics, avionics, materials science and propulsion. These technologies are collectively known as aerospace engineering.

 Due to the many aspects and complexity of the field, aerospace engineering is conducted by a team of engineers, each specializing in their own branches of science.

The development and manufacturing of a flight vehicle demands careful balance and compromise between abilities, design, available technology and costs.
The first definition of aerospace engineering appeared in February 1958. The definition considered the Earth's atmosphere and the outer space as a single realm, thereby encompassing both aircraft (aero) and spacecraft (space) under a newly coined word aerospace

LS-DYNA®  is widely used by the aerospace industry to simulate bird strike, jet engine blade containment, and structural failure.

 LS-DYNA®was used in the 911 WTC Attack Simulation http://www.cs.purdue.edu/homes/cmh/simulation/phase3/
