The Flying-V is a design for a very energy-efficient type of aircraft for long distances. This aircraft design, in which the passenger cabin, cargo deck and fuel tanks are integrated into the wing, consumes 20% less fuel than the Airbus A350, the most modern aircraft of today, due to a better aerodynamic shape and lower weight.
One of the biggest aerospace companies in the world is co-developing the “Flying-V,” a radical-looking airplane that could make aviation less expensive and more climate-friendly.
Energy-efficient flying on long distances
In the Flying-V – originally an idea by Justus Benad during his graduation assignment at Airbus Hamburg – passenger cabin, cargo deck and fuel tanks are integrated into the wing. The design is shorter than an Airbus A350, but has the same wingspan. As a result, the Flying-V makes use of the current infrastructure at airports, such as gates and taxiways, without any problems. The Flying-V also carries approximately the same number of passengers – 314 in the standard configuration – and the same amount of cargo, ie 160m3. Project leader of TU Delft, Roelof Vos: “The Flying-V is smaller than the A350, and has less surface area in relation to the available volume. As a result, the resistance is lower. So the Flying-V needs less fuel for the same distance.”

In this work, an idea for a commercial passenger aircraft was derived. Preliminary estimations indicate potential benefits of the new concept called the “Flying V” over the A350-900 reference aircraft: 10% higher L/D, 2% lower mass, a compact and simple configuration (no high-lift devices, no fairings, straight lines), and low noise (shielding of the engines from the ground).
A streamwise cut through the oblique pressurized section of the Flying V is flat and elliptical and thus it fits efficiently into airfoils. This leads to both structural and aerodynamic efficiency. A patent application for the concept was filed by Airbus .
Remarkable is also the elliptical lift distribution of the stable design using only moderate wing twist and no reflexed camber lines. A radio controlled model of the Flying V was built to demonstrate these aerodynamic characteristics and support estimations and simulations which were made in this work.
The first flight of the glider version of the demonstrator model took place in Berlin, Germany on February 28, 2014:
The first flight of the powered version of the demonstrator model was in Hamburg, Germany on April 13, 2014:
The pilot of the first powered flight was Simon Hinsch.
The Flying-V is one of TU Delft’s lines of research into making aviation more sustainable. Dean Henri Werij: “Ultimately, we have to fly entirely on sustainable energy. Co2 neutral. If CO2 is then released during the flight, for example because we then fly on synthetic kerosene, the same amount of CO2 is used to make those fuels. At TU Delft, we are investigating how we will achieve this. For example, we are investigating new ways of propulsion, such as electric and electric hybrid, the climate impact of aviation and air traffic operations, such as the airports.”
Air transport is a costly service. Its operational costs are too high. Middle class and poor people can not affect its cash.
Air transport is prone to accidents. A small mistake can be very dangerous for passengers. Hijacking of planes is easily possible.
For creating aviation facilities, huge investments are required. The cost of aero planes, construction and maintenance of aerodromes and control mechanism needs a capital expenditure.
Dr.-Ing. Justus Benad is the original designer of the Flying-V. He designed the aircraft during his internship at Airbus in Hamburg while studying at TU Berlin. We’re happy that Justus Benad has now joined TU Delft as a postdoc, working on the Flying-V.
