Title: Separable fan strut for a gas turbofan power plant

Patent ·
OSTI ID:6139118

An improved gas turbofan power plant of the type having an engine core circumferentially disposed about a longitudinal centerline, the engine core defining a primary flow passage having a radially inner flow surface, and a fan cowling circumferentially disposed outward of and concentric with the engine core to define a secondary flow passage therebetween, wherein the improvement is described comprising of: a plurality of through struts extending radially between the radially inner flow surface and the fan cowling, the plurality of struts joining the engine core and fan cowling and transferring the operational loads between the engine core and fan cowling, wherein each of the struts includes a joint having an engaged position and a disengaged position, each strut including; a radially inner portion having a radially inward end disposed on the engine core and a radially outward end with a first mating fixture; a radially outer portion having a radially outward end disposed on the fan cowling and a radially inward end with a second mating fixture, the second mating fixture adapted to cooperate with the first mating fixture to transfer the operational loads between the outer portion and the inner portion; and means to removably fasten the first mating fixture and the second mating fixture, the fastening means having an engaged position which corresponds with the engaged position of the joint and disengaged position which corresponds to the disengaged position of the joint; wherein the radially inner portion in conjunction with the engine core comprises a first module, the radially outer portion in conjunction with the fan cowling comprises a second module, and wherein the disengaged position of the joint facilitates separation of the first module from the second module by permitting divergent relative motion of the first module and the second module along the longitudinal centerline.
