Titanium Aircraft Case
Titanium aircraft casings - tseem hu ua cav cav los yog casings - yog cov qauv loj ntawm lub cav aero: kiv cua, nruab nrab kis, compressor rooj thiab turbine- rooj plaub. Lawv nqa cov rotating module loads, muaj cov roj txoj kev, thiab yuav tsum tau sib txuas lub zog tshwj xeeb, qaug zog tiv thaiv thiab lub teeb yuag. Nplooj ntawv no txhais cov kev pab cuam casing machining muaj. (Faj seeb: lub cav "cov ntaub ntawv" yog ib qho sib txawv ntawm lub dav hlau fuselage daim tawv nqaij; cov khoom no npog cav casings.)
Hauj lwm lawm
1. Vim li cas Titanium rau Cav Casings
Titanium alloy casings yog kwv yees li 45% sib zog dua li cov hlau sib npaug (qhov ntom 4.51 vs 7.85 g / cm³) thaum muab lub zog tshwj xeeb, yog li lub cav qauv sib dua yam tsis muaj peev xwm poob - ncaj qha txo cov dav hlau hnyav, roj noj thiab kev ua haujlwm emissions. Titanium kuj tiv taus cov dej, chloride thiab oxidation raug pom nyob rau hauv kev pab cuam, ncua lub neej casing thiab kev ntseeg tau. Kev khiav hauj lwm kub yog qhov kev xaiv txwv: qib titanium siv txog li 400 degree, dhau ntawm cov nickel-raws li alloys coj mus.
2. Cov ntaub ntawv
- TC4 / Ti-6Al-4V (Gr5, UNS R56400) rau AMS 4928 / GB / T 2965 - kiv cua thiab cov qauv nruab nrab.
- TC11 thiab TA15 - siab dua -kub compressor-section casings.
- Cov khoom siv nrog cov ntawv pov thawj tshuaj thiab txhua yam; forgings los yog dov rings raws li daim ntawv pib.
3. Casing Hom Machined
- Ntxuam Case thiab ntim rings.
- Intermediate thiab compressor case (thawj-stage, second-stage, multi-stage).
- Turbine-cov ntaub ntawv cov khoom thiab cov khoom siv gearbox tsev nyob ntawm kev thov.
4. Machining muaj peev xwm thiab kam rau ua
| Muaj peev xwm | Tus nqi |
| Machining chaw | 3-axis thiab 5-axis CNC |
| Phab ntsa thickness muaj peev xwm | 1.5–3 mm nyias-cov ntu phab ntsa nrog kev tswj tsis tau |
| Case diameter | 300-1600 hli |
| Machined kam rau ua | IT7-IT9 ntawm qhov tseem ceeb bores thiab flanges |
| Nto tiav | Ra 0.8-3.2 μm raws li tau teev tseg |
Nyias-phab ntsa titanium machining yog xav tau: kev ua haujlwm- hardening tendency thiab vibration rhiab heev yuav tsum nruj fixturing, ntse tooling, siab-pressure coolant thiab tswj cov khoom tshem tawm ib ntus kom tuav daim ntawv thiab tsis txhob distortion.
5. Zoo thiab ntawv pov thawj
Aero casings raug txheeb xyuas raws li tus neeg yuav khoom qhov tshwj xeeb: kev tshuaj xyuas ultrasonic ntawm cov khoom siv raw, kev tshuaj xyuas cov kua dej nkag ntawm cov tshuab ua haujlwm, cov ntawv qhia qhov ntev los ntawm CMM pov thawj, thiab cov txiaj ntsig tshuaj lom neeg thiab cov khoom siv hluav taws xob nrog tag nrho cov cua sov -number traceability. Cov ntawv pov thawj ua raws EN 10204/3.1 lossis qhov sib npaug; Kev pom zoo tshwj xeeb txheej txheem (NDT, kev kho cua sov) yog khaws cia raws li qhov yuav tsum tau ua hauv aviation.
6. Cov ntawv thov
Titanium casings pab pej xeem thiab tub rog turbofan thiab turboshaft xyaw, auxiliary power units thiab industrial gas turbines - nyob qhov twg qhov hnyav casing thiab kev ntseeg siab ntawm nruab nrab kub yog qhov tseem ceeb.
7. Txog peb
GNEE siv thev naus laus zis thev naus laus zis los ua nws qhov kev sib tw tseem ceeb, nrog rau lub xeev -thev naus laus zis tshawb fawb thiab kev loj hlob chaw thiab ntau dua 30 patented technologies. Peb txuas ntxiv ua kom zoo dua cov txheej txheem tooj liab thiab tsim cov khoom siv tooj liab tshwj xeeb nrog cov khoom siv hluav taws xob siab thiab lub zog siab kom ua tau raws li cov kev xav tau ntawm lub zog tshiab, 5G kev sib txuas lus thiab lwm yam kev lag luam tawm tshiab, thiab txhawb kev lag luam kev lag luam tooj liab kom siab -kawg thiab kev txhim kho kom zoo.
