I see no thread for this aircraft, feel free to add.

To start, the proposed CL-41T light attack with two J85, more details to come.

Don't forget the CL-41R with the NASARR radar as a trainer for the CF-104.

I can't say for certain, but given the compact nature of the airframe, I suspect they may be necessary to house, and cool, some of the radar "black boxes'.  I know of some other aircraft mods where important electronics near the engine were mounted in a streamlined blister with provisions for cooling air flow.

Jon: Thanks for the  CL-41T  :) I had no idea that so many changes were planned for attack version!

BTW, a former neighbour, Jim McManus, modelled the alternative cruciform tail for the original CL-41. He'd have been pleased to see that extended vertical fin  :D

It's one of the proposed attack versions and incorporated the most changes.

There's info on tail development in the article, which states that the T-tail was a result of chopping off
the top of the cruciform tail because wind-tunnel testing revealed stability issues.

Canadair also hoped to sell 70-to-100 CL-41s to Australia. The CL-41G Tebuan deal was meant to total a purchase of 45-to-50 airframes which was thought would strengthen the chances of an Australian Tutor sale.

Beginning in 1963, Canadair began marketing an armed trainer, counter-insurgency, and light close air support variant of their CL-41 jet trainer. The CL-41 was a low wing, T-tail, side-by-side, single engine jet trainer. The powerplant came in the form of a single Orenda J85-CAN-40 turbojet producing 2,700 lbf (12 kN) of thrust. In June 1964, a prototype was created by converting the CL-41A 26015. The conversion included a reflector gun sight, gun camera, strengthened landing gear, low pressure tires, as well as six hardpoints, two under the fuselage and four under the pair of wings. The aircraft took off in this configuration for the first time on June 9th, 1964 with pilot Ian MacTavish at the controls. Weapon trials were conducted throughout 1964 with bombs and gunpod trials conducted at RCAF Station Chatham, and Eglin AFB respectively. These were followed by an extensive weapons trials at NOTS Inyokern & NAS Patuxent River flown by USN aviators. During its gunpod trials, the aircraft mounted with SUU-11/A proved to be an exceptionally stable firing platform, the aircraft fired a total of 49,000 rounds of ammunition with repeated consistency. In 1965 the aircraft flew down to Quito, Ecuador for a series of demonstration flights, however these yielded no sale. Other failed foreign sales included Iran, Kuwait, Philippines, and Australia.  A unique proposal for the Royal Australian Air Force saw the CL-41G equipped with wingtip tanks; this would've been designated the CL-41G-4. The CL-41G's first and only sale came in March 1966 with the sale of 20 CL-41G-5's to the Royal Malaysian Air Force. The CL-41G-5's differed from the CL-41G in a few different ways, including a new more powerful engine, but perhaps that is a story for another time... A purpose built twin engine ground-attack variant of the CL-41 was later proposed as the CL-41T. The CL-41T featured two more weapon pylons, terrain following radar, and guided weapon capabilities, this never proceeded past the blueprint stage. The CL-41G prototype remained in Canada, eventually serving alongside the CL-84-1 as a chase aircraft. The aircraft was struck off the Canadian Forces inventory in January 1991, and currently resides as an outdoor display at the National Air Force Museum of Canada.

Here's an idea for those who like a bit of fun; paint a Tutor in USAF colours, and a T-37 in RCAF or Snowbirds markings, and put them side by side on a show table. Count the number of people who notice nothing wrong, those who do a double-take, and those who descend into screaming fits. Extra points for video.

I'm stealing those CL-41G pics! Even though I haven't the heart to BTS my Hobbycraft kit...I remain hopeful we'll see a 72nd version.

Wondering about a twin prop, overwing mount, Jaguar type landing gear, a Tucara. They'd be smallish engines maybe a King Air size?

The VTOL Tutor that Carl ostred about back in 2018.

CL-41J VTOL Jet Trainer
In June 1961, preliminary studies were made by Canadair that were initially tailored to the NATO V/STOL
Supersonic Ground-Strike and Reconnaissance aircraft concept, to determine the merits of a highly modified
Canadair CL-41 aircraft design as a companion type VTOL jet trainer. The side-by-side seating configuration
would provide an ideal and efficient instructional environment, as had been evident with the successful tests
and demonstrations of the first prototype CL-41 aircraft. With a standard Canadian Orenda built J85-CAN-40
engine providing the forward propulsion,
an additional three Rolls Royce RB162 direct-lift jet engines, mounted inline vertically behind the cockpit in a
lengthened center fuselage, would have provided the VTOL capability for the proposed CL-41J. A louvered,
forward opening air inlet door would be raised to a canted position for the direct-lift engines’ operation during
VTOL flight, then it would be retracted flush to the fuselage for the cruise portion of flight. A variable exhaust
system on the underside of the aircraft would have controlled the vertical thrust vector. With four thirsty jet
engines to feed, additional fuel would have been required and that would have possibly been made available
by the addition of bladder tanks in the inboard sections of the wings and in the wing-to-fuselage side fairings.
Jettisonable fuel tanks fitted to pylons under the wings would probably have been necessary for any type of a
satisfactory training mission to be accomplished. It is not known how roll and yaw were to be controlled when
the aircraft was to be operated in the VTOL regime. Pitch may have been controlled possibly by modulating the
thrust of the forward and/or rear lift jet engines.

Post by: apophenia on January 22, 2023, 09:12:27 AM
Interesting! The RB.162 exhausts sound a little reminiscent of the 'eyelid' nozzle schemed by Avro Canada half a decade earlier.

A pity that there's no details on roll/yaw control. The drawing doesn't seem to show puffer nozzles ...
Title: Re: Canadair CL-41 Tutor
Post by: elmayerle on January 22, 2023, 04:15:53 PM
They'd almost have to be there, though, even if not very evident.  I could see a devleoped version adding tip tanks for better range.
Title: Re: Canadair CL-41 Tutor
Post by: jcf on January 23, 2023, 05:10:26 AM
I think these may be the puffer nozzles. They don't appear to line up with any of the position lights.
