B.tech aerospace engineering typically specialize in one of two areas: aeronautical engineering or astronautical engineering. Aeronautical engineers focus on the design and development of aircraft, including fixed-wing aircraft and helicopters, while astronautical engineers focus on the design and development of spacecraft, including satellites and interplanetary missions.

Aerospace engineers use a combination of scientific and engineering principles to design and test new aircraft and spacecraft systems. They use computer-aided design (CAD) software to create models and simulations of pro
