Ultra Low-sweep Transonic Wing

50% REDUCTION IN FUEL CONSUMPTION BASED ON EXISTING ENGINE TECHNOLOGY AND MANUFACTURING PROCESS.

Innovative Architecture and Integration

Innovations

Boundary layer Control

Our boundary layer control system significantly reduces the wing's sweep angle and skin friction drag, enabling a specific airfoil profile and simplifying the high lift system.

Elimination of leading edge slats

The reduced wing's sweep angle and airfoil profile provide sufficient take-off, climb, and low-speed performance. A slat system is not needed, resulting in weight savings.

Extended wing span for greater efficiency

The reduced wing's sweep angle makes the front and rear spars straight. Thus, the wing span and aspect ratio can be increased for greater aerodynamic efficiency without weight penalty. Part of the wing is folded to fit existing airport gates.

Flight controls

With the straight spars providing a more robust wing structure, no high-speed aileron is needed on the inboard part of the wing, which could potentially reduce the efficiency of the trailing edge flap. All ailerons are placed on the outboard, providing a bigger lever.

Simplified high lift system

Reducing the wing's sweep angle simplifies the trailing edge flap using a single-slotted flap panel. This flap system permits a low approach speed and a suitable aircraft landing attitude.

Improved existing engine technology

The time between overhauls is crucial for an airline's business model. Using mature engine technology provides reliability and lower maintenance costs.

THE ENGINE

Existing engine technology is used to ensure a successful entry into service and address the critical issues of emissions and climate impact within a reasonable timeframe.

Contribution of the propulsion system

Increased propulsive efficiency

Due to the weight reduction resulting from the simplification of the high lift system, a heavier engine with a bigger nacelle, fan, and heat exchanger, providing better efficiency, can be installed without incurring a penalty.

Water injection system with lowered NOx emissions

Thanks to the heat exchanger, CO2 ( 70% of exhaust gases) and water ( 29% of exhaust gases) are recovered. The CO2 is used in the boundary layer control system to reduce drag and losses. The water is utilized via injection into the combustion chamber to increase efficiency and reduce NOx emissions by 80%.

Elimination of contrails to curb non-CO2 climate impact

According to preliminary data and studies, non-CO2 emissions could account for two-thirds of aircraft's climate impact via contrails. The heat exchanger, with its water-recovering system, will prevent the formation of contrails.
