These air turbines, which you probably didn’t know about before, are available on some models. in the trunk while others are found on the wing.

While it may not seem that important at first glance, it actually is is vital. Let’s talk in detail about what exactly it does and how important it is:

This propeller system is activated in an emergency and generates the electricity that the aircraft needs.

The ram air turbine contains an electric motor and is an essential tool for the aircraft. generates energy for electrical systems. It only plays a role in emergency situations, because under normal conditions the engines produce the electricity the plane needs.

The ram air turbine generates power from the airflow created by the aircraft’s speed.

These turbines, which are one of the aircraft’s backup systems, provide 5000-6950 RPM rotation for their propellers; providing the necessary hydraulic pressure to the main flight control systems and the backup electrical generator. the plane to fly safely offers.

In a scenario where two engines stop at the same time; ram air turbine takes on the job of savior.

In emergency situations, depending on the model of the aircraft, it is activated automatically or activated by the pilots. required for flight keep the most basic features This is possible thanks to the turbine.

Although we say small, the diameter of the propellers of these air turbines is on average 80 cm. So it is small compared to the airplane.

The version on the Airbus A380, the world’s largest passenger aircraft, is It is 163cm. The passenger aircraft model in which this turbine was first used was the Vickers VC10, which was produced in England in the 1960s.

The ram air turbine, which intervened in emergency situations and saved many lives, played a crucial role in a famous accident that was also the subject of the movie “Sully”.

On January 15, 2009, a plane crashed into a flock of birds in New York just after takeoff, and the plane crashed. both engines It had completely lost power. The pilots made a decision in a very short time and activated the Auxiliary Power Unit (APU) and the air turbine of the aircraft.

In this way, the pilots, who could use the electrical circuits, could continue to command the Airbus A320 aircraft, which was operating US Airways Flight 1549, and then to the Hudson River managed to make an emergency landing.

These turbines are not available in all models.

For example; The Boeing 737’s flight control system is maintained by pilots as long as the aircraft’s electrical supply is exhausted. for 60 minutes It is designed to be controllable.

It can also be used outside of passenger aircraft.

The propellers don’t need much speed to turn. Also, though small very noisy to work.
