Definitions
- the present invention relates to a new concept of supersonic aircraft, the fuel consumption and the noise level of takeoff are much lower than those of existing or planned aircraft.
- This invention supplements the prior patent of the same author, applied for in France under n ° 98 13354, where it is already proposed to use "supersonic" turbojet engines optimized for the only supersonic cruise and “subsonic” turbojet engines ensuring the greatest
- Supersonic turbojets have a small cross-section and a small dilution ratio (or ratio) while the
- This cross section of the fuselage must be as close as possible to the juxtaposition of the circular sections necessary for the retraction of the subsonic turbojets. For a large transport aircraft, this necessarily leads to a relatively large cabin (large number of seats per row) but not very high, which implies that the luggage cannot be stored in a space below the seats.
- a first embodiment of the invention corresponding to a large transport aircraft, is now described in detail with reference to the figures. It is followed by a second embodiment corresponding to a business aircraft.
- the numerical values mentioned result from the state of the prior art and from the inventor's research activities.
- Figures 1 to 5 relate to a large transport aircraft.
- Figure 1 is a front view of the aircraft showing a retracted subsonic turbojet and the other in the flight position.
- Figure 2 is a partial bottom view of the same configuration.
- Figure 3 is a partial side view.
- Figure 4 is a cross section of the passenger cabin.
- Figure 5 is a cross section in a plane where the subsonic turbojets are located.
- Figure 6 is a diagram from above of the displacement carriage of a subsonic turbojet engine and its rails-spars.
- Figure 7 is a partial front view of a business aircraft. The first description relates to an aircraft of approximately
- Each of the two supersonic turbojet engines has a dilution ratio of 0.7, an air inlet diameter of 2 m and an approximate weight of 5 tonnes.
- the thrust of each of these engines is typically 160 kN on takeoff, almost zero on subsonic cruise, 280 kN on transonic climb and 150 kN on supersonic cruise.
- Each of the two subsonic turbojets has a dilution ratio close to 10, a weight of 7 tonnes and a diameter of less than 3 m.
- the thrust of each of these engines is typically 400 kN on takeoff and 130 kN on subsonic cruising.
- FIG. 1 shows how the supersonic turbojets (21 and 22), the subsonic turbojets (11 and 12) and the fuselage (1) are placed under the wings (4).
- the right subsonic turbojet (12) is shown retracted in the fuselage (1) while the left is in the working position.
- the shape of the cross section of the fuselage (1) is close to the juxtaposition of two circles of approximately 3 m in diameter.
- Figure 3 in addition to the main elements already described, shows the vertical stiffening planes, (41) at the top and (42) at the bottom. This results in a moderate height (and therefore thickness and weight) of the drift plane (43).
- Figure 4 is an example of seating arrangement where, in addition to the vertical stiffening planes (41 and 42), also appears the internal structural reinforcement (44). These elements are not mass penalties but simply result from the optimization, in stiffness and in mass, of the fuselage. This same figure also shows how a wing spar (45) passes through the cabin. It is clear that the lower space (46) under the floor is insufficient for storing hold baggage while cabin baggage can be accommodated in large volumes.
- the cross section of Figure 5 is located at the last beams (50) of the airfoil (4).
- the right subsonic turbojet (12) is retracted into the housing (1) while the left (11) is in the working position.
- Each rests on a carriage (51 and 52) rolling on the beam (50).
- the motorization of each carriage can be on itself or in the fuselage with a cable connection as on a horizontal crane boom carriage; these motorization elements, produced according to the art already known, not being shown in the figure.
- the stiffeners (41 and 42) already described are shown as well as the door (61) for closing the left engine compartment in its open position, that (62) of the right engine being closed.
- FIG. 6 Only the left subsonic turbojet engine (11) and its carriage (51) are shown in FIG. 6. This carriage moves by rolling on the rail-rails (50 and 60); at the end of the race, it is fixed on the fasteners (53 and 63) integral with the structure of the wing (4, not drawn) to allow the motor to transmit its thrust forces.
- the open bunker doors (61 and 62) appear cut in the median horizontal plane of the fuselage.
- the electrical control and power cables as well as the fuel lines are not shown. They can remain attached to the motors (1 1 and 12) and fold with them in the hold or even disconnect from the motors (11 and 12) when the carriages (51) leave their anchorages (53 and 63).
- the total weight of the power plant is 25 tons, that is to say no more than that of similar known projects which are unable to meet current noise standards and a fortiori future ones.
- a second embodiment corresponds to a 34-ton business aircraft shown in front view in FIG. 7. Its two supersonic turbojets (21 -22) have a diameter of 0.65 m with a dilution ratio of less than 1 and its two subsonic turbojets (11-12) have a diameter of 0.95 m with a dilution ratio close to 10; in Figure 7, the right (12) is retracted while the left (11) is in the working position. For a fuselage (1) whose diameter is approximately 2 m, the geometric problem is very different from that of the first embodiment (large transport aircraft).
- the circular section of the cabin always placed under the wing (4), evolves towards a reduced surface at the level of the engine bay with only a slight widening (70) and a significant rise (71) of the bottom of the fuselage.
- the total weight of the engine is estimated at 3.2 tonnes, broken down as follows: 0.8 tonnes for each supersonic turbojet, 0.7 tonnes for each subsonic and 0.1 tonnes for each carriage. The rest of the description is similar to that of the first embodiment.
- the examples described above are not limiting.
- turbojets their transverse and axial positions, their characteristics may be different from those corresponding to the figures.
- the claim for horizontal displacement of turbofans also applies to engines (1 1 - 12) placed, as well as the fuselage (1), above the airfoil (4).
- the supersonic aircraft according to the present invention does not require major developments of entirely new engines.
- the application of the invention to an industrial production will require only a project study of which the structural calculations will be the most innovative elements.
