Design, Modelling and Analysis of a Bolted Flange NozzleIJMTST Journal
In this exercise, we designed and analyzed the bolted flange nozzle that connected the mid and lower parts
of an F1 engine nozzle. We then analyzed this bolted joint by building a non-linear finite element model in
ANSYS workbench. Our main objective is to assess and compare hand calculations and results obtained from
the ANSYS workbench of the bolted flange nozzle. We also like to determine the gaps that develop between
the jointed parts when the assembly is loaded. The Bolted flanged joints are vital mechanisms in all
pressurized systems;however, they are similarly one of the most composite parts to design. Numerous
features enterinto the finding of an effective design and analysis of a flange joint inoperation. At the entry of
the nozzle,the pressure due to the exhaust gas is calculated using 1- D gas thermodynamics. It is assumed to
fluctuate linearly along the axis of the nozzle. The pressure at the departure (z=0) is 12.17 psi and the
pressure at the entry to the mid-nozzle is 47.72 psi. In the design model, the regeneration channels are
removed. In discussion, a free body diagram is used to presume the corresponding forces on the mid and
lower nozzle. This force pair is displayed as two separate forces, each of 1000-pound force. The fluid
temperature is 700-degree Fahrenheit which causes thermal strain. We adopt that bolt is pre-loaded to 51%
of its breaking strength
A binary multiplier is a combinational logic circuit or digital device used for multiplying two binary numbers. The two numbers are more specifically known as multiplicand and multiplier and the result is known as a product.
The project represents a game on a grid of 72 LEDs (9 rows by 8 columns) in which the player must move a light representing a platform from left to right to strategically to catch falling objects.
The game is inspired from a classic game called (egg catcher) in which the player controls the position of a basket so as to catch the falling eggs. If he caught the falling egg his score increases. Otherwise, His lives decreases. The controls are two momentary push buttons. If the player successfully keeps the platform under a falling object while it is in the bottom row, the score will increment. Otherwise, the lives count will decrement. The game starts with 3 lives with the player and ends when the player loses these 3 lives. When this occurs, the game clock is disabled so the objects freeze in place on the screen and a “game over” flag will raise to indicate that the game is over.

2. • Monostabilni multivbrator ili monostabil je
multivibrator koji ima jedno stabilno stanje
a pobudom izazvana prelazi u
kvazistabilno stanje.
• Monostabil može trajno ostati u stabilnom
stanju.
• Neki monostabili imaju mogućnost
ponovnog okidanja tijekom kvazistabilnog
stanja.
4. • a) Monostabil s logičkim mrežama RC
Opis stabilnog stanja:Ustabilnom je stanju
okidni ulaz M u logičkoj nuli.
Kroz otpornik R ne teče struja i ulaz u LS je
u logičkoj jedinici.
Zbog toga je izlaz LS2 u logičkoj nuli oba su
ulaza u LS u logičkoj nuli a time je izlaz LS
u logičkoj jedinici.
Na kondezatoru je u stabilnom stanju napon
0V.
5. Opis kvazistabilnog stanja
• a) Kratkotrajnim dovođenjem okidnog ulaza u
logičku jedinicu izlaz LS ide u logičku nulu.
• Logička nula prenosi se i na ulaz sklopa LS2 jer
se na kondezatoru napon ne može trenutačno
promjeniti.
• Zbog logičke nule na ulazu LS2 njegov izlaz ide u
logičku jedinicu.
• Tada se izlaz sklopka LS2 ide u logičku nulu,izlaz
sklopka LS prelazi logičku jedinicu i završava se
kvazistabilno stanje.
6. • b) Integrirani monostabil
Proizvođači integriranih sklopova proizvode
više vrsta monostabila u integriranom obliku.
Razlikuju se po broju monostabila u jednom
kućištu zatim po svojstvu ponovog okidanja i
po vremenu oporavljanja
7. Monostabil 74123
• Dvostruki je monostabil sa svojstvom ponovog okidanja,okida se
padajućim bridom na ulazu A ili rastućim bridom na ulazu B,uz
određena stanja na ostalim okidnim ulazima.
8. Monostabil 4538
• To je dvostruki precizni monostabil sa svojstvom ponovog okidanja i
ulazom za brisanje.
Okida se rastućim bridom na ulazu A i padajućim bridom na ulazu B.
9. Raspored priključaka sklopa 555
Priključak Naziv Oznaka
1 Masa GND
2 Okidanje TRI
3 Izlaz OUT
4 Brisanje RES
5 Upravljanje CON
6 Prag THR
7 Izbijanje DIS
8 Napajanje VCC
10. Univerzalni vremenski sklop 555
kao monostabil
• Osim navedenog načina moguće su drugačije
izvedbe monostabila.
Mogu se koristiti operacijska pojačala ili integrirani
vremenski sklopovi.
Integrirani sklop 555 univerzalan je vremenski
sklop koji može raditi kao monostabili ili astabil.
Proizvodi se u TTL i CMOS tehnologiji.
Sastoji se od otpornog djelila,dva
komparatora,bistabila s ulazom za
brisanje,izlaznog stupnja i sklopa za izbijanje
izvan priključenog kondezatora.
