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...

PARIS: Bell rings changes with revised 525 specifications ....


Bell Helicopter has upped the capabilities of its in-development 525 Relentless on the back of favourable data generated from the design review process.

The super medium type will now boast a maximum gross weight of at least 8,750kg (19,300lb), up from 8,570kg, combined with the ability to carry six passengers for 500nm (926km), growing from 400nm.

However, it is confident that the production version will exceed even these revised estimates.

Primo volo .....


Bell Helicopter flew the 525 Relentless super-medium twin for the first time July 1 from its assembly plant in Amarillo, Texas, despite wind gusting to 20 knots.

The 525 performed hovers and maneuvers to assess low-speed controllability, with Bell senior test pilots Troy Caudill and Jeff Greenwood at the controls.

Caudill said the helicopter performed “extremely well. It flies better than it does in the simulator.”

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.
