Inkcazo:
I-Nano boron powder iyinxalenye yokutshisa amandla aphezulu.Ixabiso le-calorific yevolumetric (140kg/cm3) kunye nexabiso le-calorific ubunzima (59kg/g) ye-elemental boron zikhulu kakhulu kunezinye izinto ezisebenza ngamandla ezine-molecule enye njenge-magnesium kunye ne-aluminiyam.
Kwaye i-boron powder iyisibaso esilungileyo, ngakumbi i-nano boron powder inomsebenzi ophezulu wokutsha, ngoko ke ukongeza i-nano boron powder kwiziqhushumbisi okanye iipropellants kunokunyusa kakhulu amandla enkqubo yezinto ezisebenzayo.
I-Boron powder inobunzima obuphezulu bexabiso le-calorific kunye nexabiso le-calorific yevolumu, kwaye sisibaso sesinyithi esinethemba elihle lokusetyenziswa, ngakumbi kwintsimi ye-oxygen-ehluphekileyo ye-propellants eqinile.Okwangoku kuphela kwe-ramjet eyomeleleyo enokufikelela kwimpembelelo ethile yee-10kN·s.Amandla okuqhubela phambili ngaphezu kwe-kg-1, ngoko ke i-boron yenye yezona zixhobo ezifanelekileyo kwii-oxygen-lean propellants.
Ukuze kuphuculwe umsebenzi we-boron powder, i-B / X (X = Mg, Al, Fe, Mo, Ni) i-particle composite nayo ilungiselelwe ukusetyenziswa kwi-propellants.
Imeko yoGcino:
IBoron Powder kufuneka ivalwe kwaye igcinwe kwindawo eyomileyo nepholileyo.Akufanele kuvezwe emoyeni ixesha elide ukuthintela i-agglomeration ngenxa yokufuma, okuya kuchaphazela ukusebenza kokusasazwa kunye nokusetyenziswa kwesiphumo.Ukongeza, thintela uxinzelelo olunzima kwaye ugweme ukunxibelelana nee-oxidants.
