Abiadura hipersonikoko hegaldiak luzatu nahian

Joxerra Aizpurua Sarasola
29 August 2012

Abuztuaren 14an NASAk egindako saiakerak huts egin zuen. X-51A WaveRider gailu hipersonikoak, hamabost kilometroko altueran hegal eginez, orduko 7.000 kilometroko abiadura lortu behar zuen bost minutuz, baina 31. segundoan hegal baten funtzionamendu-akatsak porrota eragin zuen.

Maila horietako abiadurak Mach zenbakia erabiliz neurtzen da. Mach 1 soinuak airean eta hamabost graduko tenperaturan duen abiadura da: 1.224 kilometro orduko. Mach 1etik gorako abiadurei supersoniko deritze, eta Mach 5etik gorakoei hipersoniko. Une honetan, abiadura errekorra NASAren X-43 gailuak du; Mach 9,6ko abiadurari eustea lortu zuen hamar segundoz. Abuztuko saiakeran ez zuten abiadura errekorrik hautsi nahi, baina bai abiadura hipersonikoan luzeen iraun duen bidaiarena. Abioigintzako enpresa ugarik interesa du abiadura hipersonikoetan, batez ere bidaia luzeen iraupena murrizteko; X-51A gailuaren abiaduran bidaiatuz gero Paris-New York ibilbidea ordubetean egin liteke, eta Paris-Tokio bi ordutan.
