Jacobs responded with the Rh\u00f6nadler (in English, Rh\u00f6n eagle), ready for the 1932 Rh\u00f6n competition.  The following year both Jacobs and Lippisch had to transfer to the state owned DFS (Deutsche Forschungsanstalt F\u00fcr Segelflug) at Darmstadt, where Jacobs continued to refine the Rh\u00f6nbussard, hence the DFS Rh\u00f6nadler name.[4]The Rh\u00f6nadler was a wood-framed aircraft with plywood and fabric covering. In plan its high wing wings were straight tapered with a torsion-resisting D-box formed by ply skin ahead of the single spar.  Aft of the spar the wings were fabric covered.  The Rh\u00f6nadler wing root used a version of the thick G\u00f6ttingen 652 section, modified by a reduction of its high camber; further outboard this turned into the progressively lower camber G\u00f6ttingen 535 and Clark Y airfoils.  Dihedral was constant, to avoid the constructional complication of the Fafnir’s gull wing.  The ailerons were very long, occupying more than half the span. Though neither the prototype nor later production aircraft came with spoilers or airbrakes such devices, opening above the wing, were often retro-fitted.[4]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4The Rh\u00f6nadler’s fuselage was quite slender and entirely ply covered, including the fin, the balancing part of the rudder and a small tail bumper.  On the original version, even the cockpit canopy was a ply structure, with small, unglazed apertures  for vision.  This was progressively modified with increasing glazing into the 1935 variant’s multi-framed conventional canopy.  To avoid the wing root aerodynamic interference that the Fafnir’s gull wing was intended to avoid, the Rh\u00f6nadler’s wing was mounted just above the fuselage on a low, narrow neck or pedestal which placed the leading edge level with the top of the canopy. The high aspect ratio, all-moving horizontal tail was of similar construction to the wing, with most of the taper on the trailing edge where there was a deep cut-out at the root.  The tailplane was low set on the prototype but raised just above the dorsal fuselage line on production aircraft.  The broad chord, balanced rudder was also fabric covered.  Landings were made on a sprung skid.[1][4]Operational history[edit]At the 1932 Rh\u00f6n the Rh\u00f6nadler, flown by Peter Riedel, did not win but impressed enough to go into series production as the Rh\u00f6nadler 32, with the prototype’s wing span slightly shortened, its vertical tail leading edge smoothed by a shorter rudder balance and its tailplane raised.  This sold well, though production numbers are uncertain. The 1935 version’s alterations included a fully enclosed transparent canopy.  Schleicher built sixty-five of them, making it the top selling German high performance glider; several were exported.  A measure of the popularity of the Rh\u00f6nadler is the number at the 1935 Rh\u00f6n competition, twenty-three out of sixty contestants.[4]In the 1980s a new Rh\u00f6nadler was built from original plans and flown. It is now in the Wasserkuppe museum.[4]Variants[edit]Rh\u00f6nadlerPrototype.  Competed in the 1932 Rh\u00f6n event. 18\u00a0m (59\u00a0ft\u00a01\u00a0in) span.

There was yet another Rh\u00f6nadler, a record setting two seat glider dating from before the 1932 design.References[edit]^ a b Hardy, Michael (1982). Gliders & Sailplanes of the World.
