COVID-19 Impact

The most immediate and severe impact of the pandemic on the aircraft engine industry was the sharp decline in air travel demand. Lockdowns, travel restrictions, and concerns about the spread of the virus led to a global decrease in passenger flights. Airlines scaled back operations, parked or retired aircraft, and deferred maintenance, affecting the utilization and demand for new engines. Many airlines faced unprecedented financial challenges due to the decline in passenger traffic. This led to reduced budgets for capital expenditures, including the purchase of new aircraft and engines. Airlines that were struggling financially canceled or postponed orders for new planes, impacting aircraft engine manufacturers.

The pandemic disrupted global supply chains, affecting the production and delivery of aircraft engines. Manufacturing facilities faced closures or reduced capacity due to lockdowns and health concerns. Delays in the supply chain impacted the ability of aircraft engine manufacturers to meet production schedules, resulting in postponed deliveries to both original equipment manufacturers (OEMs) and airlines. Airlines, in an effort to conserve cash, deferred non-essential maintenance activities, including engine overhauls. This decision aimed to extend the operational life of existing engines without incurring additional costs.

While this helped airlines manage short-term financial challenges, it raised concerns about the long-term health and reliability of aircraft engines. The decline in air travel reduced the need for maintenance services on aircraft engines. MRO providers experienced a decrease in demand for engine repairs and overhauls as airlines reduced their fleets or parked aircraft. This downturn in MRO activity had financial implications for companies specializing in engine maintenance. Aircraft engine manufacturers that were in the midst of developing and certifying new engine programs faced challenges. The slowdown in aviation activities affected the testing, certification, and entry into service of new engines. Delays in these processes impacted the planned revenue streams for manufacturers.

The Turbofan Engine segment accounted for the largest share in 2023 and is expected to witness lucrative growth during the forecast period due to the growing demand for commercial jets.

Turbofan engines are known for their superior fuel efficiency compared to other types of aircraft engines, such as turbojets. The design of a turbofan engine includes a large bypass ratio, which means a significant portion of the incoming air bypasses the combustion process, contributing to improved fuel efficiency. This characteristic is crucial for airlines seeking to reduce operational costs, as fuel is a substantial expense in the aviation industry. Turbofan engines provide high thrust and power output, making them suitable for a wide range of aircraft sizes and mission profiles. They are capable of efficiently powering both smaller regional jets and larger wide-body airliners.

The ability to generate substantial thrust allows for better takeoff performance, higher cruising speeds, and improved overall aircraft performance. Turbofan engines are designed to operate at lower noise levels compared to some other engine types, such as pure turbojets. This characteristic aligns with increasing regulatory and community expectations for quieter aircraft operations. Reduced noise pollution is especially critical for airports located in populated areas, and turbofan engines help address these concerns. The high fuel efficiency and thrust capabilities of turbofan engines contribute to the long-range capabilities of modern commercial aircraft.
