AIRCRAFT PROPULSIVE ASSEMBLY AND METHOD FOR CHECKING THE INTEGRITY OF AN ENGINE ATTACHMENT OF THE PROPULSIVE ASSEMBLY
An aircraft propulsive assembly comprising a pylon and a turbomachine attached to the pylon by an engine attachment system. The attachment system comprises two engine attachments each secured to the pylon and to the turbomachine. Each engine attachment comprises at least one fitting attached to the pylon by a first main link, and attached to the turbomachine by a second main link. Each main link has a clearance-free fit. The fitting being, moreover, secured to either the pylon or the turbomachine by an additional link, referred to as a safety link, which backs up one of the main links. The safety link is in the form of an assembly with a clearance. The assembly of the safety link comprises at least one passage which receives, in a sliding manner, a tool for checking a presence of the clearance.
AIRCRAFT ENGINE MOUNT
An engine mount system having failsafe securement points. The engine mount system includes a forward mount carrying a coat hanger shackle having a spherical bearing and a cylindrical bearing. Securement of the engine mount to a support utilizes pins and bolts with a retaining double wrench washer incorporated into the final mounting structure. The engine mount system additionally includes an aft mount.
Thrust mounts with load-balancing thrust link-lever
A thrust mount assembly includes a thrust link-lever that has a first end region, a second end region, and a fulcrum region disposed between the first end region and the second end region. A thrust link-lever may be coupled or couplable to a fulcrum body of an aft engine-mount at a fulcrum position of the thrust link-lever. When coupled to a turbomachine, the fulcrum position of the thrust link-lever may be laterally offset and/or laterally adjustable relative to an axis of rotation of the turbomachine. A load translated from an engine frame of a turbomachine to an engine-mounting linkage system may be determined and a fulcrum position for the thrust mount assembly may be adjusted laterally relative to an axis of rotation of the turbomachine.
Control system and methods of controlling an engine-mounting link system
A control system and methods for controlling the position of one or more engine-mounting links of an engine-mounting linkage system are provided. In one aspect, an engine-mounting linkage system includes one or more engine-mounting links that each have an adjustable inclination angle. An inclination angle of a link may be adjusted by an actuator of the control system. One or more controllers of the control system can control the actuator and thus the inclination angle of the link by determining a control command based at least in part on an output received from one or more sensors of the control system. The controllers can then cause the actuator to change the inclination angle of the link based at least in part on the determined control command.
Rear mount for an aircraft engine
A rear engine mount for a turbomachine of an aircraft comprising a pylon. The rear engine mount comprises a beam attached to the pylon, a first and a second lateral connecting rod having an abutment and attached between the beam and the turbomachine, a three-point, V-shaped central connecting rod, of which the vertex is attached to the turbomachine, and of which the ends of the arms are attached to the beam. The rear engine mount has a plane of symmetry passing through the center of the ball joint of the vertex. The beam has, for each abutment, a buffer, wherein each abutment comes to bear against the buffer in the event of failure of the central connecting rod.
Aircraft engine mount
An engine mount system having failsafe securement points. The engine mount system includes a forward mount carrying a coat hanger shackle having a spherical bearing and a cylindrical hearing. Securement of the engine mount to a support utilizes pins and bolts with a retaining double wrench washer incorporated into the final mounting structure. The engine mount system additionally includes an aft mount.
THRUST LINK WITH TUNED ABSORBER
An assembly for connecting an engine to an aircraft, including a first support configured to be structurally connected to the engine, a second support configured to be structurally connected to the aircraft, and a thrust link. The thrust link includes a load transferring member having opposed ends each connected to a respective one of the supports for transferring engine thrust loads from the engine to the aircraft along a longitudinal axis of the load transferring member. The opposed ends have a fixed position relative to each other. The thrust link further includes a tuned absorber coupled to the load transferring member intermediate the opposed ends. The tuned absorber is tuned to absorb engine noise of at least one predetermined frequency. A thrust link and a method for reducing a transfer of noise generated by the engine to the aircraft are also discussed.
Gas turbine engine with low stage count low pressure turbine
A gas turbine engine includes, among other things, a fan section including a fan rotor, a gear train defined about an engine axis of rotation, a first nacelle which at least partially surrounds a second nacelle and the fan rotor, the fan section configured to communicate airflow into the first nacelle and the second nacelle, a first turbine, and a second turbine followed by the first turbine. The first turbine is configured to drive the fan rotor through the gear train. A static structure includes a first engine mount location and a second engine mount location.
Assembly for mounting a turbine engine to an airframe
An assembly is provided for mounting a turbine engine to an airframe. The turbine engine extends along an axial centerline and includes an engine core mount and an engine exhaust mount. The assembly includes a thrust pin linkage connecting and extending axially between a core thrust pin and an exhaust thrust pin. The core thrust pin is adapted to connect to the engine core mount, and the exhaust thrust pin is adapted to connect to the engine exhaust mount. One of the core thrust pin, the exhaust thrust pin and the thrust pin linkage is also adapted to connect to the airframe.
Propulsor mounting for advanced body aircraft
A propulsor and mount arrangement comprises a propulsor rotor and a fan casing surrounding the propulsor rotor. The fan casing receives two side mounts and a thrust link pivotally attached to the fan casing at a location that will be within 10 of a vertically lowermost location when the propulsor is mounted on an aircraft, and the side mounts being at circumferentially opposed positions, and within a lower 270 when the propulsor is mounted on an aircraft. At least a portion of both the side mounts, and a pivot point connect the thrust link to the fan casing in a common plane defined perpendicular to a rotational axis of the propulsor rotor. An aircraft is also disclosed.
