Definitions
- the present invention relates to a multi-engine aircraft and more particularly, although not exclusively, an aircraft equipped with three engines, two of which are respectively associated with the fuselage wings symmetrically with respect to the vertical longitudinal plane thereof and the third of which is provided. at the tail of the fuselage at the level of rear empennages.
- Aircraft equipped with three engines having the architecture summarized above are already known, such as Lockheed L101 1 and McDonnell Douglas DC-10 or MD-1 1.
- the third engine is located structurally and geometrically between the horizontal stabilizer and the vertical empennage of which it carries the drift.
- These aircrafts whose design dates back to the 1970s and some of which are still in service, are equipped with powerful engines to ensure long-haul connections but which generate due to their design time a high noise and high fuel consumption.
- the noise generated by the third engine is particularly troublesome for the passengers located at the back of the cabin, as well as for the residents of the airports when the aircraft is in the landing or take-off phase, since, by the em ⁇ placement of this third engine, the noise is spread all around the rear part of the fuselage.
- this architecture has been gradually abandoned to make way for a simpler architecture of the twin-jet type resulting in equal performance.
- airliners are for the most part made with a two-engine architecture such as jet engines. tors, borne symmetrically and respectively by the wings of the fuselage. Thanks to the technical progress that has made it possible to develop particularly powerful and efficient turbojets, these twin-engine jets can perform not only short and medium-haul flights, but the largest of them are also certified for long-haul flights. safely despite the use of two motors and even despite a malfunction of one of them.
- the multi-engine airplane comprising at least two first engines and a third engine which is provided at the level of the tail of the fuselage, which comprises the rear tail units, according to the longitudinal longitudinal plane of symmetry of the fuselage, said rear stabilizers defining a channel, symmetrical with respect to said longitudinal plane of the fuselage, and said third motor being arranged in the plane of symé ⁇ trie said channel corresponding to said longitudinal plane and being mounted on the upper part of said fuselage elevated and in front of said outlets, so that the output of this third motor is sensitive ⁇ ment to the input of said channel defined by said empennages, is remarkable in that said two first motors are associated with the fuse ⁇ wings respectively symmetrically by longitudinal plane verti ⁇ cal of symmetry of the latter, in that said rear empennages define the said channel comprise a horizontal stabilizer stabilized stabilizers, and in that said stabilizers horizontal stabilizer are slightly inclined symmetrically towards the rear of said fuselage to form,
- the design of the rear stabilizers and the arrangement of the third engine at the entrance of the channel considerably reduces the previous acoustic problems, since the noise generated by the third engine of the fuselage is sucked by the channel to evacuate along it, up far from the fuselage, that is to say far from the passengers located at the back of the cabin and a fortiori of residents of the airports.
- the generated noise is thus masked by the rear stabilizers of the fuselage which constitute an acoustic screen.
- the invention partly eliminates problems related to noise pollution, it is possible to return to a three-engine architecture and then to design aircraft advantageously equipped with dimensionally smaller wing engines, which are therefore less heavy and less noisy, maintaining a global power similar to a bioreactor equipped with large engines.
- the use of three engines does not imply a mass increase of the aircraft compared to a two-engine airplane (since the wing engines are smaller), and the additional mass linked to the
- the design of the tail-end channel is largely offset by the loss of mass of the undercarriages because they are smaller in size and smaller in size due to the smaller engines.
- said channel defined by the rear stabilizers sen ⁇ sibly a U-shaped whose base corresponds to the two stabilizers the rear tailplane horizontal respectively from either side of the tail of said fuselage, while the lateral branches corres ⁇ pondent the two fins of the rear vertical stabilizer, located at the end of said stabilizers.
- said rear tail can form a H whose upper part of said H corresponds to said channel.
- said third motor disposed in front of said ca ⁇ nal is arranged so that its geometric axis, contained in said vertical longitudinal plane of symmetry, passes in the vicinity of the base of said channel.
- the upper part of the tail of said fuselage is flattened in a plane perpendicular to said vertical longitudinal plane of symmetry of the fuselage.
- the horizontal empennage extends the flattened tail of the fuselage substantially conti ⁇ nude.
- said stabilizers of the horizontal stabilizer are slightly inclined symmetrically upwards to form, when they are seen in a vertical plane perpen ⁇ dicular to said vertical longitudinal plane, an open V whose point corres ⁇ pond their connection to the tail of said fuselage.
- said third motor can actuate the auxiliary power generator.
- the third motor may be the same or different from the two wing motors.
- Figure 1 is a perspective view of an exemplary embodiment of the multi-engine aircraft according to the invention.
- Figures 2, 3 and 4 are respectively side, top and front views of said aircraft shown in Figure 1.
- Figure 5 is an enlarged perspective view of the tail of said fuselage, equipped with the third motor.
- the aircraft 1 comprises three engines (of the turbojet type), of which two 2, 3 are arranged under the wings 4, 5 of the fuselage 6, respectively symmetrically relative to each other. in the vertical longitudinal plane of symmetry P of the latter, and the third 7 of which is provided at the tail 8 of the fuselage which comprises the horizontal and vertical rear tail units 9 and 10, along the longitudinal plane P.
- the reference numeral 13 represents the usual landing gear of such an aircraft.
- the horizontal and vertical stabilizers 10 define, according to the invention, a channel 1 1 which is, in this example, substantially U-shaped and which is geometrically symmetrical with respect to in the longitudinal plane P of the fuse ⁇ lage 6.
- the third motor 7 is then arranged in the plane of symmetry of the channel, that is to say the plane P, and is advantageously arranged in part su ⁇ upper 8A of the tail 8 of the fuselage, in front of the horizontal stabilizers 9 and vertical 10, so that its output 7A is located at the entrance to the channel 1 1, as shown in particular in Figures 2 and 3.
- the horizontal empennage 9 consists of two stabilizers 12 fixedly connected to the tail of the fuselage and arranged symmetrically and respectively on either side of its plane P. These stabilizers define the base of the U of said channel January 1 and, for channel to better the propagation of the noise generated by the engine, they are inclined upwards and backwards relative to the fuselage.
- FIGS. 1, 4 and 5 show that the stabilizers 12 are slightly inclined symmetrically upwards with respect to the horizon, so as to form a broadly open V whose tip corresponds to the zone 14 of the tail of the fuselage that connects them.
- the base of the channel 1 1 in U is thus slightly concave.
- these stabilizers 12 are also inclined symmetrically towards the rear, when seen from above as in FIG. 3, to form a wide open V running away from the fuse and whose tip corresponds to the zone of 14.
- the stabilizers 12 of the horizontal stabilizer 9 are provided with respective elevators 15.
- the upper part 8A of the tail 8 of the fuselage is slightly flattened in a plane perpendicular to the vertical plane verti ⁇ cal P, so that the stabilizers 12 of the horizontal tail follow approximately the upper profile of the connecting zone 14 then flattened tail, as shown in Figure 5 in particular.
- the third motor is mounted in a raised manner relative to the flattened tail of the fuselage for its entry 7B is located above the fuselage as shown in Figures 2 and 4, and that its output 7A opens in the lower part of the U of said channel 1 1, that is to say in the vicinity but at a distance from the connection zone 14 with the horizontal empennage.
- the temperature of the gases emitted by the nozzle of the engine 7 does not affect the surrounding structure, whereas the acoustic waves en ⁇ gendrée go towards the channel 1 1 according to the profiles indicated schematically in B1 and B2 ( see below) in Figures 2 and 3.
- the third motor can also be used to operate the auxiliary power generator.
- the third engine could have a different power from the other two wing engines.
