Market Scope

Market Dynamics

Drivers

Efficient power generation

The aircraft micro turbine market plays a crucial role in the aerospace sector. With the help of the unique characteristics of microturbine engines, the aircraft at present have higher performance in terms of endurance and stealth. The microturbine offers enlarged power generation units at a lower cost price, which is highly demanded by electric power companies. The microturbines are used domestically and commercially with low emissions. A simple micro-turbine has an energy conversion efficiency of 15%. Small turbine engines are efficient when used as a recuperator or regenerator, which increases the efficiency by 20-30%and they can reach up to 85% combined with thermal-electrical efficiency in cogeneration.

Restraint

High temperature

The high temperature of the microturbine directly impacts the efficiency and operation in the aircraft micro turbine market. Additionally, high temperature has the potential to cause intergranular cracks in turbine blades. The rising temperature decreases air density, which reduces the efficiency and power of turbines. The high temperature and speeds of the microturbines make it impractical for oil lubrication and ball bearing. Instead of that, air bearings or magnetic bearings are used. The temperature of the microturbine reaches as high as 1600K.

Opportunity

Hybrid electric power generation technology

This technology is a combination of multiple types of energy generation and storage, which uses two or more kinds of fuel to power a generator. The hybrid power technology is an integrated renewable energy generation technology with other energy generation systems; this technology has the potential to reduce risk for investors and ensure reliability and affordability. Hybrid energy power generation technology in aircraft offers better energy management and reduces fuel consumption by 5% compared to standard flights.

• The Electric Powertrain Flight Demonstration (EPFD) program plans to call for ground and flight tests of the hybrid electric system this decade in collaboration with Boeing and GE Aerospace.

Engine Type Insights

The turboshaft segment contributed the highest share of the aircraft micro turbine market in 2024. The dominance of this segment is observed as it is used in aircraft, particularly in helicopters, hovercraft, and UAVs. The function of a turboshaft is similar to a turboprop engine. It has the ability to take off and land vertically, which makes it highly valuable in places with limited possibilities for landing and in emergency rescue services. The turboshaft engine application is commonly used for rescue services, police, and reconnaissance purposes, as well as for agriculture. The small installation dimensions, low weight, and high static performance features offer capacity for high flight levels up to 29,520 ft. and a maximum starting height of 19.680 ft.
