Abstract

Πρόκειται για νέα σχεδίαση, με παρένθεση στενών εδρών, και νέα τεχνική, με εμφύσηση αέρα, για βελτιωμένη αεροδυναμικότητα των στελθ αεροσκαφών. Περιγράφονται οι περιπτώσεις εισέχουσας και εξέχουσας δίεδρης γωνίας εμπρός και πίσω, και της ακολουθίας διέδρων. Επίσης ανάλυση αεροτομής και μεταβλητής γεωμετρίας της πτέρυγας, με ειδική σχεδίαση για ευελιξία. Αναλύονται οι λόγοι της αεροδυναμικής ανεπάρκειας της στελθ σχεδίασης για την πτέρυγα και την άτρακτο, και προτείνονται συγκεκριμένα μέτρα για τη βελτίωσή της και συνακόλουθα για οικονομία στην κατανάλωση, μείωση της φθοράς του υλικού, και κυρίως για αύξηση της ταχύτητας και βελτίωση της ικανότητας για ελιγμούς στην πτήση. Πρώτον, προσθήκη διέδρων στις υπάρχουσες για μια προσέγγιση των βέλτιστων αεροδυναμικών διατομών κατά σημεία. Δεύτερον, έντεχνη εμφύσηση αέρα σε κατάλληλα σημεία, κατά τρόπον ώστε το πλασματικό μέτωπο του αέρα που προσπίπτει στη μεταλλική κατασκευή - αεροτομή να συμπίπτει με τα αεροδυναμικά διαγράμματα. Τρίτον, ειδική επεξεργασία του προς εμφύσηση αέρα.
