Here is one. But I think that you mean another, V/STOL Cavalier.

http://www.secretprojects.co.uk/forum/index.php/topic,1167.msg9483.html#msg9483

Nice idea about Dassault projects, but I have one suggestion - try not to pack all Dassault projects in one thread and split them in separate topics with some small amount of logic. It helps other members to find the information they want. ;)

ok for all Dassault projects .. one by topic

I have a little problem : how I can post the drawing ? ;D

I know two Dassault Cavalier : VTOL in the 1960 and a project from Alpha Jet in the 80 (I could send y the Alpha Jet "Cavalier")

I think there was many "Cavalier" projects !

Hi M. 4000 ! :)

In this topic there is a little about the Dassault's Cavaliers

http://www.secretprojects.co.uk/forum/index.php/topic,1491.0.html

For my own i said about the Cavaliers in this topic :

There is 5 "Cavaliers" in the Dassault story : 610, 620, 630, another STOL and a concurrent (but not the MD.921/922) of the SEPECAT Jaguar

Hi!
https://www.aviationsmilitaires.net/v2/base/view/Model/1998.html
"History
In 1959, Dassault noted the progress of the British P.1127 (the future Harrier) and decided to design an ADAV with the same general formula, and also the same engine Pegasus: the MD.610 "Cavalier". Ironically, it was a Frenchman, Michel Wibault, who designed this engine that he could not sell to the French government.

The MD.610, therefore, was designed around a Bristol Pegasus BE 53/8 of 19,000 lbs (8600 kgp), with two steerable nozzles on either side of the fuselage. This engine is also powered by two air intakes on each side of the fuselage. The wings are also high. The drift, the horizontal empennages and the wings are in arrow. The landing gear is also bicycle and retractable.

The most striking difference is at the level of the empennage: it is cruciform and not more conventional. The wings and the horizontal empennage are devoid of dihedron unlike the Harrier. Finally, the MD.610 uses stabilizers (kinds of crutches) on each side of the fuselage instead of the balancines wing tips.

The laden mass is estimated at about 16500 pounds (7480 kg). The size is quite similar to that of Harrier.

The MD.610 is Dassault's first known ADAV project, which briefly studies two other power lift versions: the MD.620 and the MD.630.

The first involves 5 engines, a 9,000-pound Rolls Royce RB.165 for traction and 4 Rolls Royce RB.153 for 3,500 pounds for lift. The wings are medial and the landing gear tricycle.

The second, the MD.630, has 4 engines: 2 RB.165(with deflection in the rear nozzles) for traction and 2 RB.162 for 5000 lbs for lift, all for a laden weight of 12,200 pounds (5580 kg).

These last two projects are quickly abandoned, the ratio power / weight being too weak to allow them to take off vertically.

Dassault presents his project MD.610 "Cavalier" to the military, who refuse it on the grounds that it will not be supersonic and that its only engine does not make it safe. Indeed, the reactor is too wide, the nozzles too small and unable to accommodate post-combustion. The project is therefore replaced by the Mirage IIIV, first developed in the form of Balzac. When the designation MD.620, it is reused by a ground-to-ground missile called "Jericho".

It exists in the form of a model to be built in 1/72, edited by Unicraft.

Must have passably annoyed Dassault, to lose ECAT to Breguet. His last competitor, private (public companies had been ousted of combat aircraft from the Mirage III days) Breguet - gets in a shot in the arm. And adds international cooperation in passing, something Dassault sucks at.
In the end that program, ECAT, proved a poisoned chalice for everybody
- it ballooned into the Jaguar
- Breguet still went bankrupt despite their "combat aircraft breakthrough + international partner"
- Dassault had to "swallow" them, forced by the french Gvt from 1967 to 1969
- The AdA found the Jaguar pretty expensive and redundant with the Mirages (III-E and F1 later)
