New b 52 engines

The B-52 Stratofortress is a legendary bomber that has been in service with the US Air Force since the 1950s. Over the years, the aircraft has undergone several modernization programs to keep it relevant and effective. One of the key components of these modernization efforts has been the development of new engines.

Here are some of the new engines that have been developed for the B-52:

  1. Pratt & Whitney TF33: In the 1970s, the US Air Force introduced the TF33 turbofan engine to replace the earlier J57 turbojet engines. The TF33 provided a significant increase in thrust and efficiency, allowing the B-52 to fly faster and farther.
  2. Pratt & Whitney F118: In the 1990s, the US Air Force introduced the F118 engine, which was a more powerful and efficient version of the TF33. The F118 provided a 25% increase in thrust and improved fuel efficiency.
  3. Pratt & Whitney F119: In the 2000s, the US Air Force introduced the F119 engine, which was a more advanced version of the F118. The F119 featured a more efficient compressor and turbine design, as well as improved fuel efficiency.
  4. Pratt & Whitney F117: In 2019, Pratt & Whitney announced the development of the F117 engine, which is a more advanced version of the F119. The F117 features a more efficient compressor and turbine design, as well as improved fuel efficiency and reduced emissions.

The F117 engine is designed to provide a significant increase in thrust and efficiency, while also reducing emissions and noise. The engine is expected to be certified in the mid-2020s and will be used to power the B-52 fleet for the next several decades.

It's worth noting that the B-52 has also undergone other modernization efforts, including the installation of new avionics, communication systems, and weapons systems. These upgrades have helped to keep the aircraft relevant and effective in a rapidly changing military environment.
