1. An apparatus for the suspension of an aircraft turbo-fan engine cowling to a supporting structure, said cowling including a fan duct and a core cowl, the apparatus comprising a flexmount member to be attached to the supporting structure and a pylon, said pylon including an upper pylon element suspended to the flexmount member and a lower pylon element, the lower pylon element having attachment means; a suspension device arranged in the upper pylon element and having first hook means arranged to cooperate with said attachment means on the lower pylon element, and second hook means for suspension of the fan duct, said suspension device having a first operating state in which said first hook means are coupled with said attachment means on the lower pylon element thereby to suspend the lower pylon element to the upper pylon element and a second operating state in which said first and second hook means are disengaged from the corresponding attachment means; locking means arranged when it is operated, to lock the lower pylon element to the core cowl; and drive means to actuate the suspension device and the locking means from one operating position to the other. 2. An apparatus according to claim 1, wherein the suspension device comprises pivotable rods mounted to be pivoted about their longitudinal centerlines, said rods having a number of hook means and cam means, said cam means supporting a number of suspension rods, said pivotable rods having a first operating position in which the hook means are in engagement with attachment means on the lower pylon element while the cam means allow the suspension rods to cooperate with attachment means on the fan duct, and a second operating position in which the hook means are disengaged from the lower pylon attachment means while the cam means cause the suspension rods to be disengaged from the fan duct attachment means, and actuating means coupled to the pivotable rods to pivot same about their centerlines, said actuating means responding to the drive means for pivoting the pivotable rods from one operating position to the other. 3. An apparatus according to claim 1, further comprising a locking device located in the lower pylon element and arranged, when it is operated, to lock the lower pylon element to the core cowl. 4. An apparatus according to claim 3, wherein the locking means comprise rotatable shaft means coupled to actuating means connected to be operated by the drive means, said rotatable shaft means having lock members arranged for cooperation with lock members located on the core cowl when they are rotated thereby to lock the lower pylon element to the core cowl. 5. An apparatus according to claim 1, wherein the flexmount member is adapted for attachment to a supporting structure which forms part of an aircraft, e.g. an aircraft wing. 6. An apparatus according to claim 1, wherein the flexmount member is adapted for attachment to a supporting structure which forms part of a test thrust stand for ground testing of an aircraft engine. 7. An apparatus according to claim 2, further comprising a locking device located in the lower pylon element and arranged, when it is operated, to lock the lower pylon element to the core cowl. 8. An apparatus according to claim 7, wherein the locking means comprise rotatable shaft means coupled to actuating means connected to be operated by the drive means, said rotatable shaft means having lock members arranged for cooperation with lock members located on the core cowl when they are rotated thereby to lock the lower pylon element to the core cowl. 9. An apparatus according to claim 7, wherein the flexmount member is adapted for attachment to a supporting structure which forms part of an aircraft, e.g. an aircraft wing. 10. An apparatus according to claim 7, wherein the flexmount member is adapted for attachment to a supporting structure which forms part of a test thrust stand for ground testing of an aircraft engine.
