a.ia.ion is one of the fa.test growing industries a. well a. tra.sporta.ion modes in the world. Globa. a.ia.ion contributes a.out 2% of globa. greenhouse ga. emissions a.d supports 8% of the world economic a.tivity in terms of GDP. With the phenomena. growth in a.r tra.ficking by the na.iona. a.d interna.iona. a.rliners the tota. ca.bon spa.e a.a.la.le for flying is getting progressively diminished a.d the consequentia. emission levels a.e a.so becoming a.a.ming over pa.sa.e of time. The pa.er describes the concept of evolution of Green Tra.sport system with focus on ma.ufa.turing of green a.rcra.t a.d susta.na.le green ma.keting involving green supply cha.n. This enta.ls introduction of New a.d innova.ive technologies, including a.rcra.t designing, improving opera.iona. efficiency, a.r tra.fic control & monitoring etc;combined with emission mitiga.ion efforts towa.ds susta.na.le growth of the industry, ca. ma.e enormous improvements in emission control a.d reduction in a.pla.ned a.d system-ba.ed ma.ner. These integra.ed a.proa.hes a.e proposed to be used to ha.monize the systems a.d processes tha. ca. essentia.ly constitute the suggested fra.ework of the Green a.ia.ion Tra.sport system. The pa.er, inter a.ia. discusses va.ious conceptua., stra.egic, technologica. a.d economic a.d environmenta. dimensions of the Green a.ia.ion tra.sport system with focus on crea.ing new Green Ma.keting opportunities for the a.ia.ion industry in future.

Southwa.d decrea.e of surfa.e wa.er tempera.ure wa. observed, wherea. surfa.e sa.inity did not show a.y significa.t trend.

In the present a.ticle, we introduce a.completely new regula. model for sta.ic, spherica.ly symmetric celestia. fluid spheres in embedding cla.s Ⅰ spa.etime. In this rega.d, needfully, we propose a.new suita.le metric potentia. eλ（r）to genera.e the present model. The va.ious a.a.yses on energy density, pressure, a.isotropic fa.tor, ma.s, compa.tness pa.a.eter, redshift, a.d energy condition ma.e sure the model is physica.ly via.le on the ground of model sta.s Vela.X-1, Cen X-3, SMC X-4, a.d LMC X-4. The reported solutions a.so respect the equilibrium sta.e by sa.isfying the Tolma.–Oppenheimer–Volkoff（TOV） equa.ion a.d ensure sta.ility by sa.isfying the ca.sa.ity condition, condition on the a.ia.a.ic index, a.d Ha.rison–Zeldovich–Novikov condition. The genera.ed M-R gra.h ma.ches the ra.ges of ma.ses a.d ra.ii for the model compa.t sta.s. a.ditiona.ly, this study provides estima.es of the moment of inertia.ba.ed on the I-M gra.h.
