Les Helicopteres Laflamme (Laflamme Helicopters) LAF-01
Permalink  
 


Already have a page, but I've since come across a pretty informative article on the design that convinced me that I should probably create a topic:

http://www.redbackaviation.com/les-helicopteres-laflamme-laf-01/

It's an interesting tandem-rotor design that was first brought to my attention by Stéphane back in 2011. It was first designed in January of 1981 by Réjean Laflamme, the first prototype built sometime in the 90's with a V6 Ford 3.8L car engine. Research continued in 2002 after a new facility was established, with plans to sell the design as a kit, but the project was halted on November 28th, 2004, due to lack of financial support from investors. It doesn't appear that any actual flight tests were ever done.

More (when it was shown at Oshkosh, 2004):

Jene (Rejene) damaged the 01 on it's first flight in a loss of control situation - It was an interesting project.
His cyclic controls were rigged different from the requirements of tandem helicopters resulting in narrow c/g.

Laflamme now builds tandem-rotor UAVs, they are based in Quebec.

Thanks for clearing that up. I see it mentioned often that more than a few "ground tests" took place and that Laflamme planned for an untethered flight, but the first actual flight seems to be an unspoken subject, probably for obvious reasons, LOL!

To be specific, his sons do (Laflamme Aero, Inc. is a separate business). Some history:

http://www.laflamme-ing.com/en/about-us/history/

The brothers David and Enrick Laflamme grew up among gyroplane parts of all kinds. Indeed, their father Réjean, a brilliant inventor with a passion for aviation, rebuilt two gyrocopters in the 70s and 80s: a McMulloch Super J-2 and an Air&Space 18A (formerly known as an Umbaught U-18). In the early 80s, he also sketched a new helicopter concept that would result in the first Laflamme helicopter: the LAF-01, a tandem rotor helicopter designed for the homebuilt market. A first prototype was developed from 1983 to 1996. During those years, Réjean also operated a company specialized in machining and robotics.

Growing up in this stimulating environment, both brothers undertook graduate studies in mechanical engineering. David was promoted from the university (ÉTS in Montréal) in 2002, then Enrick graduated from the same university, also in mechanical engineering with a concentration in aviation, in 2004.

While his boys were in school, Réjean and his team, including engineer André Dubois, continued to develop the manufacturing techniques and processes required for composite blades and fuselage. They also analysed and modified many components from the first prototype to finally obtain a second prototype in the early 2000s. David came back from the university in 2002 and joined the team, as did Enrick during his training courses and after graduating.

Entrepreneurs from father to sons, David and Enrick also founded a mechanical engineering firm in 2004. Ever since, backed by engineer André Dubois, they offer their customers what they do best: Finite Element Analysis (FEA) and mechanical design. Year after year, the engineering firm keeps building a strong reputation; the two brothers have gained the trust of well-recognized companies while developing new niches, including certification of lifting devices. At the same time, they have also continued development of new concepts and processes in the helicopter sector.

In 2013 the Laflamme brothers, always supported by their father Réjean and engineer André Dubois, set up the LX300 program in order to develop and manufacture an unmanned air system using a tandem rotor helicopter platform. You can follow this project in the LX300 tab of this website.

I'll get around to making another topic about Laflamme Aero projects soon.
