242 FLIGHT, 23 February 1951 CORRESPONDENCE . . . from near St. Margaret's Bay to a point near Dover Castle. And then, when he saw a break in the cliffs, just below Dover Castle, he thought his best chance was to dive in through this gap. Which he did—only, however, to make a rough landing which damaged his undercarriage and broke his airscrew. Pilots like Bleriot and Leblanc could coax these little Anzani- Bleriots up to quite a good altitude. Not that they ever bothered much about doing so, at any rate, when on the pioneer cross- country flights of those days. Flying without maps or compasses, as they did then3 their tendency was to keep pretty close to the ground in order to keep their eyes well on the railways and other prominent landmarks by which they steered their course. Epsom, Surrey. HARRY HARPER. "ARTICULATED WING" RESEARCH SOME further details are now available of the French Rey Ri,several references to which have been made in these pages during recent months. Its outstanding feature is the use of articulated or floating-incidence outer wing panels which are free to move about their attachments (described as circular discs working in torsion) within deflection angle limits cf 30 deg up or down. Equilibrium is maintained by an elastic linkage system. In all other respects the Rey is a conventional and attractive light twin built purely for research purposes. Power is provided by two Renault 6QR engines, each of 220 h.p. and fitted with Ratier v.p. airscrews. Construction is of wood and the two seats are arranged in tandem. For the time being at least, the undercarriage is fixed. The Rev's first flight, with fixed wings, was made on December 16th, 1949, the pilot being M. Leo Boyer and the flight engineer M. Marc Faure. On January 3rd this year what could be called a second first flight was made, with the floating-incidence wings in operation. Since that time it has made seven other successful flights and was to be officially demonstrated on February 13th at Melun Villaroche airfield. The idea for this flexible-wing attachment is by no means new and, in fact, a prototype was constructed in 1940 but was subse- quently destroyed during the war. Another example was con- structed at the works of Society Matra, and this one flew. Both were based on the original Rey-Rouanet patents filed in 1938. Turboprop Afterburning ? ~D EADING Mr. Talbot's letter in your issue of February ist **• reminded me that I have not noticed any references to the application of true afterburning to turboprops. Could any of your readers say whether this has been tried? At first sight it would seem to offer a comparatively cheap and simple way to improve take-off and initial climb of turboprop- equipped aircraft, even though the percentage gain in power could not be so great as with afterburning turbojets. London, S.W.n. J. C. FARQUHAR. [Residual thrust of a turboprop after two or more turbine stages have taken power for compressor and airscrew is generally very small. If an afterburner were fitted, a variable-area nozzle would also be required to obtain propulsive efficiency. The complication and weight would not be justified by the proportionate increase in thrust.—ED.] The Rey RI, built purely for research, is attractively proportioned and finished. The engines are 220 h.p. six-cylinder in-line Renaults. The elastic linkage on the present machine is the work of engineer Arsandaux in collaboration with the Societe Kleber-Colombes. Dimensions and performance details of the Ri are as follows :— Span 43ft 2£in (13.175 m) Length 30ft 2in (9.2 m) Height life I lin (3.65 m) Wing area 209.8 sq ft 19.5 m3) All-up weight 5.940 Ib (2,700 kg) Landing speed 80 m.p.h.
