Aircraft propulsion system Market driven by demand for air travel and cargo, aircraft deliveries, and fuel efficiency

All Aircrafts depend on propulsion system is to produce thrust so as to lift the object for a prolonged period of time by consuming different fuels. Presently jet engines are the workhorses of airplanes carrying millions of people, trillions of miles every year, at supersonic speed and with high safety; the failure rate is only once every million flight hours. A flight propulsion system generally consists of an aircraft engine and some means to generate thrust, such as a propeller or a propulsive nozzle.

 

Propulsion Program Problems Are Grounding F-35s

The F-35 Lightning II Joint Strike Fighter, the military’s most expensive weapons system ever, continues to be plagued by a lack of parts for its F135 engines, which cost roughly $12 million a piece, and the people and places to fix them.

 

In July 2022,  a scathing report by the Government Accountability Office (GAO) reiterated the net effect of the military’s struggles with the F135 jet engine made by Pratt & Whitney. In February, 36 of the fleet of about 450 F-35s – or about 8% – were unable to fly because they had no working engine.

 

“DOD developed a sustainment strategy unique for the F-35 engines in an attempt to balance affordability and performance,” GAO reported. “However, this sustainment strategy does not meet some key operational desired outcomes of the military services, such as having sufficient numbers of aircraft with operating engines available to perform missions. DOD has also not assessed and updated its strategy to address those desired outcomes or reflect additional challenges, such as growing sustainment costs and options for modernizing the engine.”

 

Aircraft Propulsion

NASA explains their principle, “All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan. A compressor raises the pressure of the air. The compressor is made with many blades attached to a shaft. The blades spin at high speed and compress or squeeze the air. The compressed air is then sprayed with fuel and an electric spark lights the mixture. The burning gases expand and blast out through the nozzle, at the back of the engine. As the jets of gas shoot backward, the engine and the aircraft are thrust forward. As the hot air is going to the nozzle, it passes through another group of blades called the turbine. The turbine is attached to the same shaft as the compressor. Spinning the turbine causes the compressor to spin.”

 

Several energy conversion technologies have been identified or proposed that may have potential for application in commercial aircraft e.g., solar power, nuclear power, battery/fuel cell power, and hydrogen engines. However, these advanced concepts would require major innovations, development, and changes in infrastructure before they could serve as viable alternatives to hydrocarbon-powered gas turbine engines. Electric propulsion of aircraft is a growing phenomenon in a sector subject to mounting scrutiny with regard to its environmental impact.

 

Aircraft propulsion Market

The aircraft engine manufacturing industry provides the most important component of an aircraft to enable its desired functioning. Since an aircraft engine is highly complex and sophisticated, globally the manufacturing procedure is heavily controlled by the governments.

The global aircraft engine market size was valued at USD 45.50 billion in 2021. The market is projected to grow from USD 50.76 billion in 2022 to USD 104.65 billion by 2029, exhibiting a CAGR of 10.89% during the forecast period. As the global interconnectedness increases, this figure is forecasted to exceed over 97 billion U.S. dollars by 2026 due to increasing demand for air travel and cargo.

The COVID-19 and resultant lockdowns have adversely impacted the aviation industry. This pandemic has resulted in the standstill of aircraft as a mode of transport. According to the International Air Transport Association (IATA), every year, over 2 billion people take aircraft as their mode of transportation. Due to the outbreak of COVID-19, the year 2020 witnessed over 60% loss in global air traffic, which bought the aviation industry to a standstill. Several companies have already implemented policies to restrict non-essential travel to protect their employees.

The propulsion systems market is driven by factors, such as rise in the number of aircraft deliveries,  and upgradation of airborne and unmanned aerial vehicles, among others. Increasing demand of aircrafts in the commercial aviation sector is a major factor, driving the growth of the global aircraft engines market. Increasing military budgets, especially in emerging economies and adoption of aircrafts that are equipped with advance technology are also factors propelling the demand of the aircrafts and drives the growth of the global market. In addition, growing regional unrest and increasing terrorist activities are also factors anticipated to increase demand for aircrafts in the military sector.

Increasing commercial aircraft operations are most likely to drive the growth of aircraft engines in the future. Major countries in Asia Pacific, North America, and Europe are seeing a rise in military operations, which increases the demand for aircraft engines in military aircraft. Also, replacement services will also be a factor in driving the market. These engines will also emerge useful in UAVs.

Increasing commercial aviation operations, growing international tourism, rising air passenger traffic, and increasing budget allocations for the defense sector are the key factors propelling the growth of the propulsion systems market in aircraft application

Stringent regulatory environment for aircraft engine manufacturing and MRO

The aerospace industry has very strict policies regarding the safety of both passengers and aircraft. Therefore, the aviation industry has made regulatory standards to undertake these issues and keeps on modifying them to achieve the best safety standard for the safety and improvement of the aviation industry. Hence, aircraft engine manufacturers also have to make new product developments to keep up with these standards.

One of these regulatory standards can be seen in the replacement of heavier engine components with components made of lighter metals. Thus, maintenance services offered by key players in the aircraft engines market act as a necessary service to keep up with the safety and regulatory standards of the aviation sector.

Engine component manufacturing challenges

Aircraft engines and components related to them are some of the most critical components of an aircraft. Hence, manufacturing these components is also a challenge for OEMs and product manufacturers. These products must be manufactured under the regulatory and safety requirements of the aviation industry. So, the engine system has seen some evolution in manufacturing components from high-strength steels and titanium. Companies such as General Electric have invested more in finding technologies that could ease and fasten the process of aircraft engine manufacturing. They now use 3D printers to produce various components of aircraft engines such as fuel nozzles and fuel systems with the help of ceramics. The end process consists of a heat treatment test as components of an engine must withstand temperatures and absorb millions of foot-pounds of kinetic energy on an operation.

Rising demand for fuel-efficient aircraft engines

Airlines are looking forward to aircraft engines that provide greater fuel efficiency. Some emissions caused due to aviation, such as nitrous oxide, can be reduced by engines with greater fuel efficiency. Aircraft size also contributes to the factor of fuel consumption as the bigger the aircraft higher will be the fuel consumption. Therefore, aircraft manufacturers such as Airbus and Boeing tried to produce aircraft structures that are as fuel-efficient as possible. However, many airlines are still finding smaller body aircraft more fuel-efficient.

Hence, aircraft with smaller twin-engine widebodies like Boeing 787 and Airbus A350 are considered to be more fuel-efficient. As a result, their demand is rising across the aviation industry. Rolls-Royce manufactures engines such as Trent XWB that is dedicated to Airbus A350 aircraft as it provides the best balance. The engine provides features such as best fuel efficiency, longer lifecycle, and reduced weight with greater aerodynamics, which is the key factor for aircraft engines consuming less fuel during operation.

Rising demand for zero-emission aircraft

According to Fox News, in 2018, United Airlines started printing its inflight magazine on a lighter piece of paper, which helped in reducing the weight of the magazine by 1 ounce. During that period, United Airlines had 744 mainline aircraft with a seating capacity of 210. This initiative helped save 170,000 gallons of fuel for that particular year, which ultimately resulted in profit. The airline industry profit margins are too low, and with the rising demand for aircraft, more than half of the revenue generated goes into fuel. Hence, the alternative to a conventional aircraft engine, which is an electric engine, holds a promise to eliminate the cost of fuel significantly, which will also help in saving the environment as well. Therefore, the rising demand for electric aircraft engines will be an opportunity for aircraft engine manufacturers during the forecast period

Electric plane power is much simpler — batteries power an electric motor that spins a propeller. It’s more efficient, but involves far less thrust, which is why electric planes tend to be slow. Electric propulsion can be powered by rechargeable batteries, fuel cells, or solar energy.The need to optimize aircraft performance, decrease operating and maintenance costs, and reduce gas emissions have pushed aircraft industry’s to progress more electric aircraft (MEA), and ultimately an All Electric Aircraft.

 

“The future will continue to see different and diverging requirements for the military and commercial sectors. Variable mission and adaptive capabilities will drive military programs, while time on wing and efficiency will continue to be the drivers for commercial aircraft. Material choices will differ with the technological and engineering trade-offs within each sector, and the portfolio of materials for aircraft engines will continue to grow with additional research and development, says Ernest ,” said Arvai at Pratt and Whitney
