I think it's a "Super-Caravelle" drawing on the cover. Any stuff (images) we don't have here in that Science&Vie ?

Found a NASA page with many many wind tunnel models pictures, the 733-290 included  :P :
Also some picts of Arrow Wing testing
Surprise, together with a Tu-22 blinder model !

Also some Concorde model picts there. And a lot lot more.
But anyways, I have the bad habit to post things already posted here before, so again if it's the case, i'll hide under my desk in shame for two days (but i'll take my laptop, some food and drinks with me...).
I have an old Science&Vie magazine from April 1964 which discusses SST plans and projects, notably the american ones.
It is a fascinating hindsight into a pretty naive era now lost forever.

I've found the entire article on the Internet right here, how about that. Google translation shall be able to do its job. What is lacking are the pictures, pretty beautiful ones.

What is pretty clear from this magazine, is that Concorde started as "Super Caravelle" which mean, Paris - Algiers and back, 4500 km total (sonic booms rattling southern France and Spain ? no problem !). No way that aircraft ever crossed the Atlantic. Then it started growing heavier and heavier, more fuel for more range. The magazine (April 1964) say that Concorde remain marginally trans-Atlantic - 5 years before first flight, 12 years before commercial service. Which says how much SST were pushing the edge of technology, with very little margin.
Concord was the size/speed it was because thatís what was considered technically feasible at the time. Indeed the final aircraft had a payload range which was very marginal;- to be within fuel regulations, the flight plan, going east bound would routinely declare Shannon as the destination only to divert to New York based on a satisfactory fuel state being achieved a pre determined point on the outbound route  ( the Pax knew nothing of this), AirFrance pressurised the fuel to balloon the tanks to get more in and regularly towed the aircraft to the runway to avoid taxi out feul burn. Aerospat/BAC didnít have an aircraft which achieved payload range until mid 1974, after 18 versions of the wing leading edges flight tested to wring out every last fraction of a percent from the performance.....amongst a raft of other things. The problems of making your declared payload range get worse the bigger the aircraft;- ie the squared vs cubed divergence which would have very much been on Lockheed mind with their SST proposal.

The ďSuper metalĒ Titanium is very overrated;- A study done in the mid 70ís based on replacing the aluminium in Concord with Titanium, only for it to  show that it would only achieve about 20% of the required fatigue life. Redesigning the airframe to achieve the fatigue life added so much weight it killed the payload range. BTW - The SR71 fleet leader only did a few thousand hours, with many of the other airframes had less than one thousand upon retirement;- A civil aircraft typically is designed to last 30-50 K flying hours.

I too laugh at Boeing plans for a hypersonic considering the airport noise but even more astounding is Musks plan to fire a BFR daily from the Hudson close to New York;- the supersonic arrival shock is very alarming as well;- itís a sudden noise that sounds like a bomb going off, yeah sure New York is going to accept that.
Early Aircraft Projects / Re: Italian Heavy Fighters

Years ago i made several art work about the Santangelo heavy fighter called also "Sturmovino" for the better know Russian Sturmovik, because can do ground attack with the cannon under belly.
italian bf 110?  ;D
Naval Projects / 1973-74 Spansh Guided Missile Destroyer Project
« Last post by Tzoli on Today at 08:04:00 am »
Conway's All the World Fighting Ships 1947-1991 mentions a Spanish destroyer project from the 1970's: 1973/74 but offers very little info about the project:
3 ships to be built
127mm OTO-Malera gun system(s)
Anti ship and Anti air missiles
COGOG propulsion for 34knots
ASW Helicopter(s)

Does anybody heard of this project or know more about it?

Another request for help, this time I could use drawings for the British 40mm STAAG mount preferably the Mark 2 variant both top and side views, and the Mark VII single mounting.

Picture from Alamy shows launch bridle on the RA-5. Because of the reconnaissance 'canoe' a twin hookup arrangement was probably used. Possibly a single bridle hookup on other models.

^^ Posting a brief snippet that suggests that HCSW will not be air-breathing...

As both ARRW and HCSW rely on well-understood rocket-based propulsion, they are considered a lower technical and schedule risk to meeting the urgent requirement for near-term air-launched hypersonic weapons capability. For the mid-to-longer term, development of more operationally flexible air-breathing systems also continues. Both Lockheed Martinís Skunk Works and Raytheon are working under contract with DARPA to develop the Hypersonic Air-breathing Weapon Concept (HAWC), a scramjet-powered missile demonstrator similar in concept to the Air Force Research Laboratory/Boeing X-51A scramjet-powered vehicle that exceeded Mach 5 in a 2013 flight test.

Raytheon, which is partnered with Northrop Grumman Innovation Systems (formerly Orbital ATK) on the scramjet for HAWC, is also in final negotiations with DARPA to develop and test a TBG glide demonstrator. Raytheonís newest work is believed to be supporting DARPA development of a ship-launched TBG for the U.S. Navy. In July, Lockheed was awarded a $40.5 million Navy Hypersonic Booster Technology Development (HBTD) contract, also believed to be related to this effort.
Wonder if, back when they launched the Fuze Replacement program in 2011, they imagined they'd be putting test videos on YouTube one day.
