How does a jet engine/gas turbine work?

How does a jet engine/gas turbine work?

Forward motion forces air into the intake which is a convergent duct where it is compressed (causing a temperature rise).

Fuel is added and combustion takes place increasing the volume. The expanding gasses accelerate to the atmosphere through the exhaust duct nozzle producing a propulsive jet.

Why do we use Jeppesen charts/plates?

Why do we use Jeppesen charts/plates?

Jeppesen charts and plates are simplified and uniform.

What is MDA?

What is MDA?

Minimum decent altitude (non-precision), the lowest altitude, expressed in feet above mean sea level to which descent is authorised on final approach or during circle-to-land maneuvering in execution of a standard instrument approach procedure where no electronic glideslope is provided.

If not visual between MDA and MAPt, a Go-around must be initiated.

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.

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

Name the different aircraft categories, speeds and on which speed these categories are based.

Name the different aircraft categories, speeds and on which speed these categories are based.

Aircraft categories are based on Vat (in knots):

A <91

B 91-120

C 121-140

D 141-165

E 166 - 210

What are the problems associated with icing?

What are the problems associated with icing?

Drag penalties (additional weight)

Less controllability

Can you explain to me what Mach tuck is?

Can you explain to me what Mach tuck is?

Mach tuck is a nose-down pitching moment experienced as an aircraft passes Mcrit.

Mach tuck is a form of longitudinal instability that is caused by the centre of pressures rearward movement (caused by the shock wave) behind the centre of gravity.

What does the abbreviation MSA mean?

What does the abbreviation MSA mean?

Minimum Safe Altitude.

What is wing loading?

What is wing loading?

Wing loading is the loaded weight of the aircraft divided by the area of the wing.

The faster an aircraft flies, the more lift is produced by each unit area of the wing. Correspondingly, the landing and take-off speeds will be higher and the high wing loading also decreases maneuverability.
