The fantastic, all-metal wind tunnel model pictured below was rescued from the Convair salvage yard in San Diego around 1963 by a Convair engineer; he was able to "free" both this model of the F-106X and a model of the F-111. The salvage yard at that time was open for four hours once a month, a real bonanza for employees searching for parts for home projects. I recall foraging in Cessna's Prospect plant scrap yard back in the 1950s and coming up with occasional treasures, but never a wind tunnel model!
This model of one version of the F-106X is in a large 1:20 scale and was undoubtedly used in Convair's Low Speed Wind Tunnel at speeds up to 300 m.p.h. This tunnel, located at Convair's (Convair Division of General Dynamics in 1961) plant, has been donated to the San Diego Air & Space Museum; information on the tunnel may be viewed by clicking here. Use the back arrow to return to this page. This tunnel (LSWT) is in current use by numerous manufacturers. The model was also likely used in the Lewis Research Center's transonic and supersonic tunnels as described in the 1969 NASA report, TM X-52585. In this report, a 1:20 scale model of the F-106B was sting mounted to study the flow field. You can study this report by clicking here. It is worth viewing as the F-106B test model is very similar to the F-106X model and the method of sting mounting is the same.
The model measures 41" from the tip of the pitot tube to the tail and the wingspan is 23"; both aluminum and steel are used for the model's construction. All materials and filler are original with the exception of the blue stripe/tape; no restoration has been made to the model. A few screws are missing, apparently the sole minor parts deficiency.
If you would like to research the history of the F-106, an excellent place to start is the F-106 Delta Dart Website.
The Convair F-106X was proposed in 1956 as a follow on configuration for the F-106; the "X" (Model 8-28/8-29) was to have more power with the JT4B-22 engine, rectangular intakes, canard layout and a longer nose with a 40-inch dish radar. The F-106X was proposed as an alternative to the Lockheed YF-12. The project was later re-designated F-106C/D, with "C" being the single-seat version, the "D" being the two-seat version. At one time the Air Force had considered acquiring 350 of these advanced interceptors, but the F-106C/D project was cancelled on 23 September 1958. Contemporary drawings and art work depicted the "X" as having the canard surfaces located alongside an elongated engine intake, unlike the F-106X model design offered here. There are, however, drawings from 1956 of an "X" version which is similar to the model's layout; you can view these report illustrations by clicking here. The F-106 became the prime ADC interceptor in the 1960s and a competent air-to-air fighter. There is mention of another proposal in 1967 of an F-106X design to fill the gap when the YF-12 fighter was cancelled; this F-106X didn't materialize. This later proposed design is not believed to incorporate the canard layout and would have been subsequent to the use of this model by many years.
This one-of-a-kind, metal wind tunnel model of the proposed Convair F-106X is a very rare find and is presented here for documentary and historical purposes.
Funny thing is one can begin to see the roots of the Convair Model 200 design here.circle-5 said:Factory model of the Convair F-106X IMI with canards, variable ramp intakes and a bigger engine.

Sorry, no time to attach the pictures to this post. :-\
Wow your father was in an F-106 unit!! F-106 is very very beautiful aircraft.ChuckAnderson said:
Yes, and before that he was with an F-102 unit that was originally stationed at Paine Field AFB here in Washington state, that eventually went to the Philippines and South Viet Nam.blackkite said:

He worked in the fire control systems on both aircraft types, whose function I believe was to target hostile aircraft and fire the missiles.
Back in 1965, he (and his unit) took part in the William Tell competition at Tyndall AFB in Florida, where interceptor units from the USAF, ANG and RCAF had live fire exercises against what I believe were Firebee drones. The USAF aircraft were F-102s and F-106s, and the RCAF guys flew F-101B Voodoos.
