Leading from the front: Innovation in Aerospace &Defence (A&D) industry

The aerospace and defence industry is a key area for innovations worldwide. It has stimulated innovations with broader implications and in many cases has impacted daily life in a positive way. AI, GPS navigation, commercial aeroplanes and satellites are just some examples of innovations that have made great changes.

For example, aircraft design has undergone radical innovations since the early 1900s, which has led to significant improvements in performance. The approach to technological improvements in flight design has changed from the high-speed model to the most reliable, fastest and cheapest version.

Trends in R&D innovations can be classified into four main categories:

Articles:
A few decades ago, 70% of the aircraft was made of aluminium. Other materials, such as composites, titanium, graphite and fiberglass, have limited applications. However, the use of pure aluminium in modern aeroplanes has been reduced by 20%. The structural materials of the aircraft now include compositions. For engine parts and critical components, opt for low weight and high-temperature insulating materials for better fuel efficiency. This has led to the search for new material development and a look at the previously abandoned materials industry in search of poor machinery.

Graphene/carbon (CNT) nanotubes for ceramics and motor structures are more demanding and pine than the materials used for different manufacturing processes and equipment. With the uniqueness of the application in the industry, there is a combination of materials in A&D that will continue to change in the coming years.

Design:
Aircraft primarily use carbon-based fuels, such as gasoline or kerosene, but as oil resources decrease and penalties for greenhouse gas emissions increase, the future of aviation depends on finding a source of energy. alternative. The solution to this challenge is the development of electric aircraft (or hybrid aircraft) that use energy for aircraft systems. The idea is to significantly reduce fuel consumption by improving overall energy efficiency. Low battery storage capacity and weight and power density are some of the challenges that require innovative thinking.

Commercial jet turbofans are getting bigger. Larger fans and higher bypass ratios mean higher propulsion efficiency and lower fuel consumption. Turbofans have a 15-20 bypass ratio compared to 10-12.5 for conventional engines. But its larger size forces changes in the design of the wing and the landing gear and, presumably, in the design of the aircraft and the location of the engine.

In the era of deflationary profit margin environments and the need for innovative designs, modelling, simulation and rapid prototyping can play an important role in the development and testing of the new design with lower risk and lower cost, reducing So time to market. A&D engineers can explore the effects of highly complex physical phenomena on typical product designs. They can imagine, create, optimize and evaluate many design alternatives for engines, wings, radar systems and other components that have the potential to transform the industry, without investing in extensive physical prototypes or wind tunnel tests.

Technologies and manufacturing processes:
Pressure on aircraft production continues to increase in the A&D industry, driven by an increasingly significant increase in commercial passengers and defence costs. Today, the transition to Industry 4.0 seems to be the most effective solution to increase factory productivity.

Industry 4.0 is seen as a transformative force that transforms not only the manufacturing infrastructure but also the development of products and services. This trend is driven by rapid advances in digital technologies such as the Internet of Things, Big Data, Artificial Intelligence and Digital Practices: cooperation, mobility and open innovation.

Huge investments have been made in the A&D industry to facilitate this revolution, which is not limited to sectors such as 3D printing, factory automation, advanced analysis and post-marketing forecast management, but in more capabilities and strategies Integrals for business transformation with Industry 4.0.


The A&D industry is at the forefront of the use of 3D printing, both in proto and in manufacturing. Aerodynamic engine manufacturers increasingly use this technology for blades and other components
