Questa tesi esplora i progressi all'avanguardia e le prospettive future nel campo della propulsione spaziale, sottolineando i propellenti verdi basati su ADN/GAP, i carburanti sostenibili per l'aviazione (SAF) e i programmi pionieristici SKYLON e SABRE. Lo sviluppo di nuovi sistemi di propulsione è fondamentale per l'esplorazione dello spazio profondo e le manovre satellitari. Questo studio approfondisce le tecnologie di propulsione avanzate, tra cui propulsori elettrici e chimici, che promettono maggiore efficienza e ridotto impatto ambientale. I propellenti basati su ADN (dinitramide di ammonio) e GAP (polimero di glicidil azide) sono all'avanguardia nelle soluzioni di propulsione sostenibile. Questi propellenti verdi offrono vantaggi significativi rispetto ai tradizionali carburanti a base di idrazina, tra cui minore tossicità, prestazioni più elevate e rischi di gestione ridotti. Questa sezione esamina le proprietà chimiche, le metriche delle prestazioni e le potenziali applicazioni dei propellenti ADN/GAP utilizzando il software CEA nelle missioni spaziali attuali e future. l'industria aeronautica che si sforza di ridurre la propria impronta di carbonio, SAF emerge come un'alternativa praticabile al carburante per aerei convenzionale. Questa tesi valuta i processi di produzione, i benefici ambientali e le sfide di integrazione di SAF. Considera inoltre i quadri normativi e le implicazioni economiche per un'adozione diffusa nell'aviazione commerciale. Lo spazioplano SKYLON, alimentato dal rivoluzionario motore SABRE, rappresenta un significativo balzo in avanti nell'ingegneria aerospaziale. La tecnologia del razzo ibrido a respirazione d'aria del motore SABRE offre prestazioni senza precedenti, consentendo capacità di orbita a stadio singolo (SSTO). Questa sezione fornisce una panoramica completa dei progressi tecnici, delle tappe fondamentali dei test e degli sforzi collaborativi alla base del progetto SKYLON. Discute inoltre i potenziali impatti di SKYLON e SABRE sul futuro del trasporto spaziale e dei voli spaziali commerciali. Integrando approfondimenti da questi campi diversi ma interconnessi, questa tesi mira a presentare una visione olistica delle future tecnologie che modellano la propulsione sostenibile nell'aerospazio. I risultati evidenziano il ruolo fondamentale dell'innovazione nel raggiungimento di soluzioni sostenibili dal punto di vista ambientale ed economicamente praticabili per i settori spaziale e aeronautico.
