Agustaman Posted February 13, 2012 Report Share Posted February 13, 2012 Era un po' che mi chiedevo quanto ci avrebbe messo la Bell a svegliarsi... mai capito perché sono usciti dal 139, ma adesso almeno hanno un prodotto posteriore alla guerra del Vietnam in quella categoria Link to comment Share on other sites More sharing options...
tornado4ever Posted February 14, 2012 Report Share Posted February 14, 2012 In effetti hanno trovato una soluzione davvero simile al AW189. Molto minimalista ed ordinato il cockpit. B.525 aw189 Link to comment Share on other sites More sharing options...

Tuccio14 Posted March 19, 2012 Report Share Posted March 19, 2012 (edited) Praticamente ormai la configurazione/disposizione dei motori e dei volumi in genere sta diventando per la maggior parte degli elicotteri quella inaugurata da Agusta con il 139 e con le ultime versioni del 109. Sta succedendo quello che tra i liners può definirsi il fenomeno Airbus, ovvero la configurazione fusoliera/ala/motori/carrello imperante è quella del 320. Anche del 737 od onor del vero, non fosse per quell'ala troppo vicina al suolo che limita il potenziale di sviluppo dei motori, ma è un'altra storia...

Flaggy Posted January 18, 2020 Report Share Posted January 18, 2020 Considerato che il FARA di Bell, l'Invictus, prende elementi proprio dal Relentless, si spera che non ne prenda anche l'andazzo, ma ho i miei dubbi in proposito: le problematiche tecniche sono sempre dietro l'angolo anche quando si deriva qualcosa da qualcos'altro, figuriamoci quando si piglia qua e là (parti del rotore in questo caso) e il resto lo si rifà da capo... Il problema sempre più comune in aeronautica, vista la scarsità di progetti, è la difficoltà nel mantenere in know how e di rispondere rapidamente alle sfide e alle problematiche tecniche.
