Technological Advancement in Aerospace Industry

Aerospace and Defense | Jun, 2023

The aerospace sector is continuously evolving and registering positive growth with the introduction of commercial spacecraft, including satellites and suborbital flight, Advanced Air Mobility (AAM) vehicles, and advancement in space technologies. Improvements in the infrastructure, business models, and supporting architecture are also contributing to the growth of the sector. As a consequence, urban air mobility and space tourism are gradually becoming a reality. The use of multisectoral technologies including 5G, cutting-edge satellite systems, 3D printing, Big Data, and quantum technology, among others, has made it possible to scale up and modernize air and space operations. The aerospace sector includes the design, development, production, and operation of airplanes, spacecraft, satellites.

The social, political, and technological changes that are driving this transition in the aerospace industry include environmental legislation, rising fuel prices, and developments in batteries, sensors, and connection. All of these changes are paving the way for the creation of autonomous, effective, and more electric airplanes. Besides, customers and authorities are pressuring the aviation and defense (A&D) sector to provide more fuel-efficient aircraft. Consequently, new rules to restrict emissions, such as carbon dioxide and nitrogen oxides (NOx), and to reduce noise have emerged. However, the green movement in the A&D sector, however, goes beyond simply following the law and protecting the environment since cost is another factor for the dynamic shift. As a result of the growing complexities, entrepreneurs are working hard to streamline the A&D industry's processes, products, and operations.

Here are some of the trends currently dominating the Aerospace industry.

Terrain Awareness and Warning System (TAWS)

The adoption of the terrain awareness and warning system (TAWS) has resulted in a significant reduction in accidents caused by controlled flying into terrain (CFIT). CFIT accidents can occur due to multiple reasons such as flight crew distraction, malfunctioning equipment, or miscommunication in air traffic control. With CFIT, generally pilots are unaware, and the situation becomes too challenging to handle on that moment. As an airplane navigates shifting terrain in a variety of weather situations, the technology offers life-saving information and acts as an essential layer of protection. TAWS gathers GPS data on an aircraft's position, speed, and direction, as well as its altitude and configuration, and compares it to a database of natural and artificial obstacles on Earth. The U.S. space shuttle program's radar topographical pictures, DOD data, and other information were combined to create this incredibly precise database. TAWS is able to deliver a variety of alerts when the aircraft's location and tracking information are superimposed on it. Key cautions issued by TAWS:

  • warnings regardless of the topography around when the sink rate is too great
  • warnings if terrain separation suddenly decreases
  • warnings when there is a severe fall of altitude following launch
  • If the landing gear or flaps are not set up properly, warnings will sound
  • If the aircraft has strayed too far from the glideslope, warnings will sound
  • Callouts for excessive bank angles
