Τα αεροπλάνα του μέλλοντος
Συντάχθηκε απο τον/την Κωνσταντίνος Παπαμαργαρίτης   

Τα αεροπλάνα του μέλλοντος θα σας μεταφέρουν σε μακρινούς προορισμούς μέχρι να… πείτε «κύμινο».

Τα επιβατηγά jet θα μπορούν να πετούν με ταχύτητα πέντε φορές μεγαλύτερη από την ταχύτητα του ήχου, που σημαίνει ότι η πτήση από το Λονδίνο στη Νέα Υόρκη θα πραγματοποιείται σε λιγότερο από… μία ώρα!

 

 

Σύμφωνα με μια έρευνα από το Ινστιτούτο Μηχανολόγων Μηχανικών της Μ. Βρετανίας αυτά τα αεροσκάφη θα μπορέσουν να κατασκευαστούν μέχρι το τέλος του αιώνα, ως μέρος των προσπαθειών για να μπει το Ηνωμένο Βασίλειο στην πρώτη γραμμή της μελλοντικής αεροδιαστημικής καινοτομίας.

Μια πιθανή ημερομηνία τοποθετείται μετά το 2075.

Η συγκεκριμένη μελέτη κάνει λόγο για επιβατηγά τζετ αυλοαεριωθητές υπερηχητικής καύσεως που πετούν με ταχύτητα 4.000 μιλίων την ώρα (πέντε φορές μεγαλύτερη από την ταχύτητα του ήχου).

Το γρηγορότερο αεροσκάφος που υπάρχει τώρα είναι ένα scramjet της NASA, το οποίο πιάνει ταχύτητα 7.000 μιλίων την ώρα.
