In the aviation industry a reduction of fuel consumption by up to 50% is possible!

 

The results of our experiments show that a proper integration and optimization of an airplane with the new ZETJET engine can achieve fuel savings which couldnít be imagined before:

1. There is no need for an external nacelle. A ZETJET engine can be placed behind or inside the body of the airplane in the slipstream thereby avoiding additional air drag. Gross thrust can be used for the propulsion of the airplane (sail plane).

2. The ZETZET engine can exploit the secondary air flow (air flow from the side) to generate a significant additional thrust. The use of aerodynamic profiles (similar to sail boats) is simple and cost effective. This is new and was never described before

3. The ZETJET engine shows an increase in efficiency gains compared to the FANJET with increasing speed. This effect has a huge hidden potential and needs to be explored further. The models in use today expect the air to come from the front. Experts applying those models have claimed that ZETJETs would not even move. This is new and was never described before.

ZETJETs show characteristics that canít be explained with the known models and theories applied for the design of airplane engines. We have ventured into unchartered waters and created first scientific evidence that a reduction of the fuel consumption by up to 50% in the aviation industry is possible and likely.

We can move a step further in the decarbonisation of the aviation industry. A commercial use of hydrogen/fuel cell/electric propulsion solutions for airplanes are now more likely.

ZETJET engines and concepts are a breakthrough technology able to renew the aviation industry radically.

 

 Experimental comparison between ZETJET(red) and FANJET(black)
Configuration A:
(modern, classical airplane)


ZETJET is empty, aerodynamic profiles are covered, drag belongs to the body.

FANJET contains the electric impeller, air flows in from the front, jet is directed backwards
Configuration B:
(classical airplane with ZETJET in external nacelle)

ZETJET contains the electric impeller, aerodynamic profiles are working, drag belongs to the body, air flows in from the side, jet is directed backwards, engine is placed behind body.

FANJET casing is empty, no propeller, drag of empty nacelle remains as load.
Configuration C:
(new airplane design with ZETJET integrated in body)

ZETJET contains the electric impeller, drag belongs to the body, air flows in from the side, jet is directed backwards

FANJET nacelle is removed, no extrag drag from FANJET
 
Power at 45 m/s: ca. 8.2 kW (=100%)

Power at 45 m/s: ca. 7.8 kW (ca. 6% fuel savings)

Power at 45 m/s: ca. 5.8 kW (ca. 30% fuel savings)

Expected fuel savings applying Breguet formula:
Mid-range flight: ca. 40%
Long-range flight: ca. 60%

FANJET modern, classical airplane with external nacelle

First optimization step: ZETJET in external nacelle

Second optimization step: ZETJET integrated in body of a new airplane design
