Aerospace manufacturers are faced with the challenge of designing systems and components that have to be safer, more reliable, and cheaper to operate, deliver better passenger comfort, and have less environmental impact than their competitors. In addition, they have to systematically reduce development times in order to get new products to market earlier.

Aerospace engineers design aircraft, spacecraft, satellites, and missiles. In addition, they test prototypes to make sure that they function according to design. The main difference between aerospace and aeronautical engineering can be summed up very simply, according to Bruce R. White, Dean of the College of Engineering at University of California, Davis. “Aeronautical engineering tends to focus on flight and activities within an atmosphere,” White said, “while aerospace engineering includes the atmosphere, but also extends into applications in space, where there is no atmosphere.” Both aeronautical and aerospace engineers are involved in areas such as aerodynamics, flight stability, and aircraft control, as well as traditional engineering not only issues related to aircraft systems. The following is a list of activities performed by an aerospace or aeronautical engineer: Design, develop, manufacture, and test aircraft and aerospace products and systems.Maintain, overhaul, and repair aircraft parts and systems for reliable operation of the aircraft.Develop in-depth understanding of aerospace materials and quality standards, such as aerospace material standards.Understand and comply with regulatory requirements and standards such as Federal Aviation Regulations, Canadian Aviation Regulations, and European Aviation Safety Agency.Develop acceptance standards of aerospace parts, systems, and components.Inspect parts for malfunction, damage, or repair ability for safe and reliable operation of aircraft.

High strength and lightweight components are the primary interest in all automated industries. Aerospace industries have spent significant efforts to develop new materials to reduce payload and fuel consumption. The latest generation of Aluminum-Lithium (Al-Li) alloy received extensive attention due to their inherent properties and considered as a futuristic material. Aluminum alloy 2099 belongs to the latest generation of Al-Li family. It has many superior properties such as low density, high strength & stiffness, superior damage tolerance, excellent cryogenic and corrosion resistance (Alam and Sinha 2019; Goebel, Ghidini, and Graham 2016; Ma et al. 2011; Rioja and Liu 2012). AA 2099 has many applications such as automotive engine component, structures and plating to cryogenic containers, fuselage structures, wing stringers, and other stiffness dominated design (Jabra et al. 2006; Lin and Zheng 2017).

Interdisciplinary research tends to be a hot spot and has gradually become a key area for significant breakthroughs. Especially in the space propulsion field, aerospace technology has been increasingly combined with other technologies,1–3 such as micro-electronics, laser techniques, and nuclear technology. Since the 1960s, nuclear power sources4 (NPSs) have been developing rapidly and gradually have become the dominant propelling technologies in earth orbital missions, lunar and planetary surface missions, and other cases where long-lifetime, self-sufficient, or high-energy density is required. As a propulsion system, whether it serves as a reactor power source or radioisotope battery,5 NPS is usually treated as a heat or electron source. A conversion system6 is always needed to create thrust from NPS, such as thermoelectric, thermionic, Brayton, etc. Fission-fragment propulsion, radioisotope sail, and other methods to get thrust directly from a nuclear reaction have been studied as well,7,8 however, those studies haven’t gone as far as the former two.
