AW&ST January 24,2000 by Michael A. Taverna

Eurocopter/Westland/Agusta Tiltrotor in the 10 ton 20-25 passenger class (significantly larger than the Bell Agusta 609). A flying demonstrator was planned to be flying by 2005-2006.

The European Joint Tiltrotor will benefit from earlier design efforts:

Eurocopter Eurotilt (derived from earlier Eurofar design)

Agusta Erica

Compound helicopter devised by GKN Westland ( I have no pics from it altough I have the following references if anybody can help; AW&ST July 12, 1999 p.23 and Feb 22.1999, p.47)

unlike that TW68, the Eurofar's wing seem to be not deflected for VTOL

Does Europe still have a Tilt Rotor project, beyond the BA-609?

AFAIK, no ! There was the 2GETHER proposal, as a joint development by Eurocopter
and Agusta, the name meaning "2nd Generation European Tilting Highly Efficient Rotorcraft",
but this project ws axed to a lack of sufficient funding.

Before they cancalled Eurofar, the had done some work on a demonstrator - never seen line drawings for it, but have this photo

Interesting detail of EUROFAR was, that the nacelles were only partially
tiltable, contrary to most other tilt rotors.

I've said this over at What-If but I'll be darned if that Erica doesn't just look like an Mu-2 with tilt-rotors (but then again the Mu-2 was darn aerodynamic)

Talk to Professor Gareth Padfield at Liverpool University or visit the Flight Sciences dept web there

By the way, does anynone happen to know what >>Erica<< stands for? Is it some sort of abbreviation? European....?? I haven´t got the faintest idea what it could mean.

Nah, I think it's a perfect name! Everyone knows all aircraft are female by default and if you're gonna slap on some nose art right there half the job's already done for you ;)

Intersting page about construction of a wind tunnel model of the erica tilt-rotor. The pdf mentioned at the bottom of the page is worth down loading.

Note that the project moved from the tilting half-nacelles to the tilting half-wing.

In the same way we have the Eurofar project
(1982-85)

It's probably to save head space into the fuselage.
Traversing wing spars (cantilever) reduces usually the available height inside the cabin at the wing/fuselage junction.
Notice that most modern business jets have the wing similarly mounted beneath the fuselage.
