Speculation: A Dassault 3-engined RJ

Sun Nov 07, 2004 11:02 am

Hi folks....
Being a huge fan of the trijet (727, DC-10, L-1011, etc) I was wondering if should Dassault ever decides to get into the RJ market, could they design a 3-engined RJ around their 7X, 900 & 2000 bizjet? Or would the cabin of these 3 models be too narrow to be useful for a 2-2 layout? What would the pro's & cons be for a 3-engined RJ? All replies, opinions & smart-assed comebacks welcomed.  Wink/being sarcastic Regards.

I love tri-jets myself... i think they are the most interesting and classy looking designs, but

an RJ would be used for fairly short trips. Im not sure their would be too many advantages to the trijet design in this case. It did work for the BAe-146, but one could argue in many ways, the BAe-146-300 didn't as well as it could have because it hard a hard time competiting with DC-9-30s and B737-200s. The clear advantage the BAe146 had was its very short take off and landing ability.

Maybe this is the angle you could market a tri-jet rj on? Unfortunately, it is going to be a long time before if ever, we see something like the good old 727 produced again. I think the tri-jet's design best hope is still for long-haul flights.

Here's a thought. The 777 and A380 will have similar engines. Not quite but sort of in the same way the 767, MD-11 and 744 have similar engines. How about a trijet 450 seater using RR trents, or the other 777 engines? Ultra long range, so its ETOPS free, yet less maintenance than a quad, and should be able to get off shorter runways that the 777-300.

Trijets just don't make sense under ANY circumstances at this point.

The cabin of the 900 or 2000 series aircraft would not be near large enough for regional jet use, especially if overhead bins were to be included.

Such an aircraft would essentially need to be completely re-engineered, to include more cabin space (longer), baggage storage space, etc.

No Falcon design (50,900,2000) has an overly long airframe.

It would be cool to see how they would do in the commercial RJ market..3 engined or 2 engined. There is a huge completion center for Dassault here in LIT and I can't wait to see the 7X!! With a length almost the same size as a CRJ2, a wingspan 11 feet shorter than a 732, and a range comparable with a 777-200, it will be one hell of a business jet.

Um, the 777 has much more powerful engines than the A380. Quite frankly, ETOPS has killed the long haul trijet and cost cutting has killed the short haul trijet

To be honest I would be surprised if Dassault hasn't looked at the RJ market ditto for gulfstream. But then decided that it was outside their core market.

I don't think a 2000 or 900 based fram would be that tight of fit.

ERJ's don't exactly have wide cabins either.

Meant to respond to this earlier.

Mx on a trijet is way more difficult than on a quad.

this idea is over 10 years old.

Dassault explored a RJ based on the 50/900 and choose not to pursue it.

The Falcon 2000 is not a tri jet, just the 50 and 900.

How many people can the 900 carry now?

As much as I would love to see a commercial trijet flying again, i don't think it is exactly economical and I don't think anyone would go for it. Probably the same reason the Avro 4 engine RJs didnt sell much and the ARJX totally bombed and put the Avro company out of business.

ClickHappy,

This idea was explored 30 years ago! It even got to the hardware stage. It is a little known fact that Dassault built a Falcon 30 in the early 70s.

It was to be an "RJ" in every sense of the word. It had 30 seats and was to be followed by the Falcon 40, which was never built. The airplane didn't sell and I'm not really sure what became of the single flying example. Here's a picture of a model....

and even better, the real thing....

OK, somebody, somewhere, is this worth any RR points?

SLCPilot, for what it's worth I added you to my RR user list  Wink/being sarcastic Thanks for that history lesson. I'd never knew about the Falcon 30. Does anyone know what happened to that sole example? Regards.

Thanks Flagship....I'll return the respect...

I'll do a little more research, but my money says the airplane was probably chopped up. It seems the Falcon 30 joins the list of "could have's" along with the twin engine DC-10 and other designs that had promise, but whose timing was off....

Fly Safe,
