Presented below is the operatin cycle of the jet Malls flap eprmtem. Prior to engine starting and later on during the satire starting prOcsd." until the engine speed reaches 66 l,2'% according to the high-pysssurr rotor flaps are open, the outer Jet nozzle area diameter being the (Fig.55). equal to 6700M With the high-pressure rotor r.p.m. Increasing over 6e, the flaps viii eonverge,the diameter of the throat being 530 on and remaining within these liaite up to the moment when the engine control lever is get at the MAXD= RA1'Ip atop. Setting the engine control lever to the MI1F1art1M A'MnTA2'IOK position will open the flaps increasing the throat diameter to 610 ma, which will switch om the adjustable afterburner. When moving the engine control lever from the MIX AUOMEYPATION to the FULL AUGMENTATION stop, the flaps will smoothly open and when finally the engine control lever rests against the FULL AUO pin p , the flaps will be fully opened, the nozzle throat disaster coning to 675 set, Mien the engine control laver moves backward, the flaps operate in the reverse sequence. In this case, however , the flaps will diverge ehangiag the 530-mm din. of the throat for the 675-10-mm diameter somewhat later, when the hiCh-pressure rotor r.p.m. will be equal to 60 % of the rated value (instead of 66*2%). This difference in r.p.m. at the moment of flaps divergence and oomr vergence when assuming the 675 10-mm din. is provided to prevent multiple open- ing and closing of the jet nozzle flaps when flying at engine speeds close to the high-pressure rotor r.p.m. equal to W . In the event of failure of the automatic follow-up ystem the jet nossie flaps are controlled by the emergency system. To change over to operation from the emergency shutter control system, turn on the NOZZLE EMERGE= CONTROL switch on the left-hand panel; this will disconnect the automatic follow-up system for flap control, after which thrust adjustment under the augmented conditions becomes impossible. In this case, with the engine running, the flaps Can assume the follow- 3n' positional (a) the engine control lever being moved within the range between the CUT-OFF atop and the post ion corresponding to 66+ % of high-pressure rotor throat. The flaps will remain converged to this extent up to the moment when ,;top (corresponding to 100? according to the OYPT-le panel lab). With the engine control lever in this position,the f??:1 augmentation rating will be reached and the nozzle flaps will fully diverge increasing the throat diameter to 675-10 M. the engine control lever is set to ? position elose'to the FULL AUGMENTATION Checking o2erntion_of let _oiz a flaps with cut-off engiiu - As it is impossible to simulate the operation of the Sy-4 unit with a cut- off engine, a full-scope checking of the nozzle flaps under these conditions cannot bo performed.

In case condensed water is found under the aircraft covers on the skin, remove the covers, wipe the akin dry with pieces of cloth, dry the covers and place them on the aircraft. 1 9.
