Does the N1 compressor produce thrust?

Does the N1 compressor produce thrust?

Yes, with the modern high bypass turbofans the N1 compressor works as a huge propeller, it takes a big mass of air and gives it a relative small acceleration.

Around 70% of the air will bypass the core of the engine, only 30% of air will be compressed further and will eventually go through the combustion chamber.

What is a turbo fan?

What is a turbo fan?

A turbofan is a type of jet engine, similar to a turbojet.

It essentially consists of a ducted fan with a smaller diameter turbojet engine mounted behind it that powers the fan.

Part of the airstream from the ducted fan passes through the turbojet where it is burnt to power the fan, but the majority of the flow bypasses it, and produces most of the thrust. They are mainly used commercially because they are highly efficient and relatively quiet in operation.

If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?

If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?

Apply opposite aileron to the direction of the roll.

What is an FMA used for?

What is an FMA used for?

Bright yellow lights will light up in the cockpit.

What do airplanes have to guard against reaching Mcrit?

What do airplanes have to guard against reaching Mcrit?

Barber pole on the ASI, flying at a Mach number at altitude and audible warnings.

Does a jet have a critical engine? Why yes or no?

Does a jet have a critical engine? Why yes or no?

No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.

You are flying in a straight line on an airway when your company calls and requests you to return to base, what will you do first?

Inform ATC.

Why is anhedral used instead on some aircraft?

Why is anhedral used instead on some aircraft?

Anhedral:

compensates for the wing sweep improves roll maneuverability

What are the benefits of a free turbine?

What are the benefits of a free turbine?

A free turbine is a turbine that is not directly connected to the compressor. This allows the compressor to rotate at a different speed than the turbine. Since the turbine speed is coupled with the propeller, this allows for the propeller to be maintained at a constant ideal speed.

Another advantage is that free turbine engines can be designed to be more compact than their single shaft counterparts

How does an altimeter work and which errors can an altimeter experience?

How does an altimeter work and which errors can an altimeter experience?

When an aircraft climbs, the static pressure in the instrument case decreases, which allows the enclosed capsule to expand.

This in turn moves the needle on the instrument to indicate a corresponding altitude.

During descent, the opposite function applies.

Altimeter errors can originate and vary from:

Instrument Pressure Time-lag Barometric Density Temperature Blocked static port
