Turbine engine provided with means for absorbing stresses from the thrust of the engine thereof
Turbine engine, comprising two structural annular casings ( 16, 22 ) which are interconnected by connecting rods ( 54 ), characterized in that the turbine engine further has at least one accessory gearbox ( 40 ) which is fixed to a first of the casings ( 16 ) and which is connected by the connecting rods to the other of the casings ( 22 ).
1. A turbine engine, comprising two structural annular casings which, considering the direction of flow of the gases in the engine from upstream to downstream, are axially located respectively upstream of a high pressure compressor and downstream of a high pressure turbine, and which are interconnected by means for absorbing thrust forces from the engine having connecting rods, wherein the means for absorbing thrust further have at least one accessory gearbox which is located outside said two structural casings, which extends between said two structural casings, which is directly fixed to a first casing and which is connected by the connecting rods to a second casing.
2. A turbine engine according to claim 1 , wherein said the at least one accessory gearbox is fixed to a hub of an intermediate casing.
3. A turbine engine according to claim 1 , wherein the connecting rods have a first end articulated on the at least one accessory gearbox and a second end which is connected directly or indirectly to an inter-turbine casing or to an exhaust casing.
4. A turbine engine according to claim 3 , wherein the second end of the connecting rods is articulated on the inter-turbine casing or the exhaust casing.
5. A turbine engine according to claim 3 , wherein the second end of the connecting rods is connected to the inter-turbine casing or to the exhaust casing by downstream suspension means of the turbine engine.
6. A turbine engine according to claim 5 , wherein the second end of the connecting rods is articulated on the suspension means which are mounted on the inter-turbine or exhaust casing.
7. A turbine engine according to claim 5 , wherein the suspension means comprise a support member which is designed to be fixed to an aircraft strut.
8. A turbine engine according to claim 1 , wherein the means for absorbing thrust comprise a single accessory gearbox which is generally V or U-shaped and which comprises two lateral arms which are interconnected by a middle portion, the middle portion being fixed to the first casing, and the arms each being connected by a connecting rod to the second casing.
9. A turbine engine according to claim 1 , wherein the means for absorbing thrust comprise two independent accessory gearboxes which have an elongate shape, each accessory gearbox comprising a longitudinal end which is fixed to the first casing and an opposing longitudinal end which is connected by a connecting rod to the second casing.
10. A turbine engine according to claim 1 , wherein the connecting rods are substantially parallel to one another and to the longitudinal axis of the turbine engine.
11. A turbine engine according to claim 1 , wherein each connecting rod comprises a first end articulated on a yoke which is rigidly connected to a casing of the at least one accessory gearbox, and a second end articulated on a yoke which is rigidly connected to a member which is mounted on the second casing.
12. A turbine engine according to claim 11 , wherein the member is a ring which is mounted around the second casing and on which suspension means are fixed for suspending the turbine engine from an aircraft strut.
13. A turbine engine according to claim 11 , wherein the member is a support member for suspension means for suspending the turbine engine from an aircraft strut.
14. A turbine engine accessory gearbox, comprising a casing bearing means for directly fixing to the turbine engine and means for connecting to connecting rods, wherein the casing is structural in order to ensure a transmission of force between the means for directly fixing to the turbine engine and the connecting means.
