GE Aviation's CT7-2F1 turboshaft engine, designed for super-medium class twin-engine helicopters, received a type certificate from the United States Federal Aviation Administration (FAA).

According to GE, the CT7 engine has a thrust class of 2,000 l. with., equipped with a new high-pressure turbine with an increased resource, an electronic control unit, as well as a system for monitoring the performance and metering of HUMS (Health & Usage Monitoring System).

At Bell, it is noted that during testing, cars with this type of engine have accumulated more than 1,000 flight hours and more than 1,350 hours of the total engine operating time.

In addition to Bell-525, the CT7 is also used by the main competitors of this aircraft - Leonardo AW189 and Sikorsky S-92.

It is known that the engine will be available with the GE Aviation company's comprehensive service True Choice Flight Hour program.

Engine certification is another step towards obtaining a type certificate for the Bell-525 itself, which is expected in the United States by the end of 2019. They are hoping to certify the super middle class helicopter in the United States later this year. This model is positioned as the first commercial helicopter with an electric remote control system. This is the heaviest machine ever produced by the company - its take-off weight is 9 tons.

The company notes that the first plan is to use the sun in the interests of the oil and gas industry, search and rescue operations, and for emergency medical assistance. In addition, Bell-525 is suitable for VIP transportation. The maximum capacity of the machine will be 20 PAX.
