Claim 0:
1. A thrust reverser system for jet engines comprising:
a tailpipe having an internal surface in contact with engine gas flow and an outer surface, wherein the tailpipe has a front end and an aft end;
a pair of actuator-in-actuators disposed on the tailpipe;
a pair of clamshell-type doors comprising longitudinal edges and configured to fully surround the tailpipe when in a stowed position,
a pair of driver links each connected to a corresponding clamshell type-door of the pair of clamshell-type doors;
two fixed and two moveable fairings disposed proximate to the aft end of the clamshell-type doors and configured to reduce aerodynamic drag;
a first locking arrangement disposed on a first side of the tailpipe;
a second locking arrangement disposed on a second side of the tailpipe;
wherein each of the first locking arrangement and the second locking arrangement comprise:
a rolling or fixed body lock disposed proximate to the front end of the tailpipe;
a compression spring in mechanical communication with one of the pair of actuator-in-actuators and one of the pair of driver links;
a pair of S-shaped hooks with a first end and a second end disposed on the aft end of the tailpipe and in mechanical communication with one of the pair of clamshell-type doors at the first end and one of the moveable fairings at the second end; and
a solenoid configured to actuate the pair of S-shaped hooks.
