| Dave Stern Renton, WA | Greetings: Very nice X-7 presentation. Public domain imagery is lacking of the Marquardt RJ-55 and RJ-59 ramjet engines that actually pushed X-7 to its highest speed. I have a 60 or so page Convair Super Hustler proposal to the USAF; a two-man hypersonic cruise vehicle that used two RJ-59 motors. Also, some letters from Marquardt stating they tested both RJ-55 & RJ-59 on the X-7; however, they were working on a larger or increased H.P RJ-59A and is so stated in their letters I found with the proposal. The RJ-59 was paired to the Super Hustler, and artist drawings show the motor but no photos seem to be available. The booster for Super Hustler also used the RJ-59.
I'm searching for X-7 images with large diameter ramjet engines as they would be the RJ series, or the engine images themselves. I have loads of aviation-aeropsace imagery to trade for this material. I secured images of the Wright XRJ-47W 48 inch ramjet motor images for the XB-64 Navaho cruise missile. You are welcone to E-mail me. Thank you D Stern 01/11/2011 @ 15:27 [ref: 35457] |
| Guy E. Franklin Deatsville, AL | The Lockheed X-7 (dubbed the "Flying Stove Pipe") was an unmanned test bed for ramjet engines and missile guidance technology. It was carried aloft by a B-29 or B-50 Superfortress carrier aircraft. The booster ignited after launch and propelled the vehicle to a speed of 1,000 mph (1,625 km/h). The booster was then jettisoned, and the underslung ramjet took over from that point. The X-7 eventually returned to Earth, its descent slowed by parachute. A maximum speed of 2,000 mph (3,250 km/h / Mach 4.31) was attained, setting a record for fastest air-breathing aircraft. A total of 130 X-7 flights were conducted from April 1951 to July 1960.

| Kevin Bodkins Abilene, TX | Just wanted to let everyone know that there is an X-7 in Caddo Mills, Tx about a mile south of the airport on FM1565. It's enclosed in a chain link enclosure, but you could still get a decent picture of it. I'm not sure what mark it is. It's painted black with some very faded markings on it. 09/24/2002 @ 22:32 [ref: 5751] |
