CAPRA and MATRA Aircraft Designations

CAPRA and MATRA are great for unbuilt aircraft projects since not a single aircraft designed by Robert Roger was actually flown :D Most of this has been covered by Jacques Moulin on his Aerophile blog - - but I thought it should be summarized in English.

For the most part, the CAPRA designation style is simply 'R' (for designer Roger Robert) followed by a type numeral (in the usual French blocks of 10). The R.20 record aircraft was an exception, also being referred to as the RR ('Roger Robert', without numbers), the S 20 (S for 'Sport'), or even the S 200.

The only built and flown Matra aircraft were postwar designs by fighter pilot André Moynet (better known for Matra's involvement with LeMans racing cars). It seems that Société Engins MATRA was to build prototypes of Moynet's executive aircraft designs which were then to be built in series by Sud-Aviation.

The Moynet Jupiter series were assigned Moynet type numbers. The first Matra-built example was the M 360-4 (for 4 seater, presumably for Lycoming IO-360, 4-seater). The second prototype was the M 360-6 Jupiter ... presumably for 6-seater, although the engines were now IO-540s :eek:

Many thanks for that, Hesham.

I'm attaching an Aerotecnica designation list here. It is off-topic for CAPRA/MATRA but Jean Cantinieau was employed at Aerotecnica until the firm's collapse in 1962. Cantinieau could have been involved with the design of all of these Spanish helicopters.

AC.11 : More powerful, Lycoming-engined development of MC.101

AC.12 : AC.11 deriv., monocoque fuse., rotor diam. 8.50 m, x 12
-- Spanish Air Force Aerotecnica AC.12 designation: EC-XZ-2
- [Project] Turboshaft deriv. of AC.12 [unknown engine type]

AC.13A: [Andre Bruel-designed Nord N.1750 Noreife sold on by SNCAN]

AC.14 : [enlarged 5-seat AC.13A, 400 shp Artouste IIB, rotor 9.60 m]
-- Spanish Air Force Aerotecnica AC.14 designation: EC-XZ-4, x 10

AC.15 : [Project] AC.14 devel. powered by 1 x 260 hp Lycoming O-435-V

AC.16 - AC.20: [Hypothetical designations]

AC.21 : [Project] 12-14 seat transport, 2 x Turbomeca Turmo III*
-- * AC.21 had AC.14-style ducted tail-boom, devel. ended in 1962


So many projects, so little time...

Many CAPRA/MATRA designs were patented under Robert's name. Go to Espacenet and do a quick search for ROGER AIME ROBERT - you will truly boggle at the amazing aircraft mixed in among the detailed plumbing.
