Guy at 1:17 is just filled with.... enthusiasm. One Hell of a professional ground crew you got there! One's dancing a jig while the other sits on a fiberglass ladder.

my god that is amazing. and its no wonder that the f15 has such an insane thrust to weight look at those damn engines absolutely massive.

THE EXHAUST NOZZLE MECHANISM: Three basic elements comprise this mechanical system: (1) a power driven primary (convergent) nozzle area setting system; (2) a balance beam or pressure load balanced convergent nozzle system: and (3) an aerodynamically adjusting or floating divergent system. Primary nozzle throat area control is achieved through an exhaust nozzle control system which senses critical engine operating parameters (inlet temperature, burner pressure, fan rotor speed, power lever angle), integrate these into a nozzle area requirement and transmits a nozzle positioning command to an airmotor. The airmotor powers two 0.8 cm (0.3 in.) diameter flex cables which rotate at a maximum speed of 20,000 rpm. Aft or downstream of the two airmotor cables is a series of five equally spaced ball screw actuators which extend and retract, in a synchronized system through interconnecting drive cables. The ball screw actuators have a stroke of 18.5 cm (7.3 in.) including adjustment. Retraction opens the nozzle and extension closes. The actuator rod extensions act together through a set of curved links to axially position a synchronizing ring which is supported in each degree of freedom, except axially, by a bearing and track system within the nozzle support structure. Axial degree of freedom is controlled by the actuators. A bellcrank and linkage system is activated by Long Links connected to the synchronizing ring. These transform the linear motion of the extended actuator rods into a variable diameter hoop of connecting links that bring the nozzle system into equilibrium after changing nozzle throat area. Each Long Link transmits motion and loading to a bellcrank attached to the outer post on each of the Convergent Nozzle Flaps. The bellcrank rotation drives the two tangentially aligned Short Links connecting the bellcrank of one flap to each of the adjacent Convergent Flaps. When connected to all bellcranks and flaps, the short links form a 360-degree contiguous hoop loading element which is set into radial position by synchronized bellcrank rotation. The balance beam, or pressure load balanced convergent nozzle section, is comprised of a series of Balance Flaps connected to the Convergent Flap through a series of hinged joints. The Convergent Flaps pivot about their fulcrum points or support hinges. The Balance Flaps are supported at their forward end by art interconnecting hoop of links internal pressure vessel loadings are reacted out of the Balance Flap on the forward hoop of links and at the rear hinge. The hinge loads transferred from the Balance Flap react upon the Convergent Flap forward hinge to counterbalance the internal pressure induced turning moments imposed on the Convergent Flap System.

How is the motor that powers the actuator gnazzos louder than the jet engine itself?

Those nozzle actuators are very loud, are they electric motors making the noise?

@@billpoturica5308 It is not hydraulic, it is air like Base Loiter said. The Nozzles are actuated mechanical actuators that are driven by the CENC (Converget Exhaust Nozzle Control). The CENC is driven by 13th stage bleed air from the N2 Compress, also known as the HPC (High Pressure Compressor). The noise that you hear is from the air when it exits the CENC. Now all this info is for the F-15 C/D & E models because they use P&W engines, either the F100-PW-220 or 229. The new F-15EX has GE engines and the nozzles on them have hydraulic actuators.

The Eagle, grown beyond the wildest dreams of men, it's known, was first to reach the heavens, above all the world below. By steel and wood, by sweat and blood, on wings of woven cloth, he slipped the surly bonds of earth to touch the face of God. But knowing times of trouble, and the devils they may bring, are only thwarted by the will to fight, he raised his mighty wings. Prepared for, thus guarding peace; for liberty, his love, he shall deliver unto evil: death, dealt swiftly from above Cap the fuel, Seal back the door, Turn fuel to fire, Let this monster roar

@@jrftworth This is RAF Lakenheath, a Royal Air Force station which happens to be in the UK. Just a side note, who the hell puts the month before the date? It’s illogical and pointless. Day, month, year is in perfect chronological order in terms of length. There is no reason for the US to insist on using such a useless format for the sole sake of being “different”.
