 air around conventional aircraft creates a lot of noise

The shape of the plane is what is known as a "blended wing" design. This hybrid design uses the wings of a conventional plane smoothly blended into a wide tailless body.

As turbulent airflow, generated by irregular surfaces, causes noise, the designers tried to make the airframe as smooth as possible.

The aerofoil shape of the body means that it also contributes to the aircraft's lift, meaning it can make a slower approach on landing, again reducing noise.

The improved lift also means that the plane can do away with flaps on the wings, which are a major source of airframe noise on conventional aircraft.

Because the design does not need a tail, used to provide additional lift and stability on conventional craft, it also cuts down on turbulent airflow and noise from the back of the plane.

The design, made of lightweight composites, also improves the fuel efficiency of the craft whilst cruising.

ENGINES

The engines are embedded into the body of the aircraft

The engines of the SAX-40 are embedded within the blended wing design with the air intakes on top. This means that the upper surface of the aircraft shields people on the ground from engine noise.

The engines are also mounted deep within the intake ducts, lined with mufflers, to maximise the noise absorption.

By embedding the three engines in the aircraft frame, it also reduces drag and therefore noise.

The "ultra-high bypass ratio turbofans", as they are known, are also arranged in a novel way to minimise noise output.

Instead of having one large fan, they have three arranged side-by-side. The smaller fans means the noise from each one is easier to absorb with surrounding "acoustic liners", or muffling materials.

EXHAUSTS

The exhaust system optimises the engines performance

The output of the engines is channelled through what is known as a "variable area exhaust nozzle".

This means that the cross sectional area of the exhaust can be changed to generate different amounts of thrust and to maximise the engine's performance.

At take-off the exhausts would be open-wide to generate the maximum amount of thrust. Whilst cruising they would reduce in size to burn fuel more efficiently.

They can also be rotated, or "vectored", to generate thrust in the
air around conventional aircraft creates a lot of randomness 

 The condition of the plane is what is known as a " blend fender " design. This hybrid design use the fender of a conventional plane smoothly blended into a wide anurous body. 

 As turbulent airflow, generated by irregular surface, causes randomness, the designers try to lay down the airframe as smooth as potential. 

 The aerofoil shape of the torso means that it besides contributes to the aircraft's elevator, meaning it can make a slower overture on landing, again reducing noise. 

 The improved lift also means that the plane can do away with flaps on the wings, which are a major source of airframe noise on conventional aircraft. 

 Because the design does not need a tail, used to supply additional lift and constancy on ceremonious craft, it also cuts down on turbulent airflow and randomness from the back of the airplane. 

 The design, made of lightweight composites, besides improves the fuel efficiency of the craft whilst cruising.

 The engine of the SAX-40 are embedded within the blended wing design with the tune intakes on top. This mean that the upper surface of the aircraft shields people on the ground from engine randomness. 

 The engines are also mounted deep within the intake ducts, lined with mufflers, to maximise the noise preoccupation. 

 By embedding the three engine in the aircraft frame, it also shrink drag and therefore noise. 

 The " extremist - high bypass proportion turbofans ", as they are known, are also arranged in a novel room to minimise noise output. 

 Instead of having one large fan, they have three arranged slope - by - side. The smaller fan means the noise from each one is easier to absorb with surrounding " acoustic liners ", or muffle materials.

 The exhaust system optimises the engines performance 

 The output of the engines is impart through what is know as a " varying sphere exhaust nozzle ". 

 This means that the hybridization sectional area of the exhaust can be changed to render different amounts of thrust and to maximize the engine's performance. 

 At take - off the exhausts would be open - across-the-board to generate the maximum amount of thrust. Whilst cruising they would reduce in size to bite fuel more efficiently. 

 They can also be rotated, or " vectored ", to generate thrust in the
