Nagler helicopters... from Germany to the USA

NAGLER HAFNER

R-I Revoplane single seat experimental helicopter
R-II Revoplane single seat experimental helicopter (1932)
(nd) Helicogyro no details (1934)


NAGLER-ROLZ

NR 54 one-man portable helicopter
NR 55 one-man portable helicopter


NAGLER HELICOPTER

XNH-1 Heliglider strap-on' rotorcraft to cross rivers or other obstacles with two solid rockets at the tips of the rotor (1952)
XNH-2 Heligyro similar to XNH-1 but added 2-cyl opposed engine driving a pusher prop (1952)
NH-120 ultra-light single-seater with two rotors: one main rotor with collective and cyclic pitch control, the latter by a hanging stick, and one smaller anti-torque rotor (1954-55) [N74054]
Model 130 Convertocraft* convertiplane consisting of Aeronca K fuselage minus wings plus two-bladed rotor powered by six solid fuel rockets placed at the tip of each blade (1954)
NH-140 one-place light helicopter with two co-axial rotors and a 70hp McCulloch engine (1956)
Model 141 Vertigyro (see VERTIGYRO VG-1 below)
NH-160 "single-seat helicopter, incorporating lessons learnt from NH-120, and while the general principle remains the same, the positions of the rotors were changed; two coaxial rotors, each on either side of the center of gravity (1955-56)"
NH-161 may have been a project to re-engine the NH-160 with a more powerful (85hp de-reated from 120hp) McCulloch
Model 193 Honcho (Honcho 100) one-place helicopter with AiResearch 85-90 gas turbine feeding compressed air to the rotor (1972) [N1750Z]
Model 200 Yellow Bird two-place derivative of Honcho 100 with Continental TC140 engine (Turboméca Palouste license) (1973)


VERTIGYRO

(nd) modified from a PA-22 Tri-Pacer and fitted with a modified Brantly B-2 rotor (1960); entirely new tail with a small vertical fin and a horizontal tail plane with vertical end plates; only tested as pure helicopter [N598X]
VG-1** Vertigyro Piper PA-22 Colt aircraft fuselage with conventional engine; rotor system was driven by turbine engine, enabling craft to be flown as gyroplane, helicopter, or combination of both (Jan. 1964) [N5395Z] >> now Harry R. Van Giesen VG-1 [N2198L]
VG-2/C/P planned production two-seat derivative of VG-1 (1970)
VG-4 four-seat derivative of VG-1


NAGLER AIRCRAFT

Model 202 two-place derivative of Honcho 100 with Solar-T-62-Titan gas turbine (1973)
Model 205 low-cost circulation-control rotor helicopter proposed to the Naval Air System Command in 1972
Model 217 Phoenix pressure-jet design study using a steam engine powerplant
Model 228 Phoenix homebuilt lightweight helicopter started by Bruno Nagler and continued by Heligyro Corporation (Scottsdale AZ); may later have been continued around 1977/1978 by Eagle Helicopter Corporation of Grand Island, Nebraska


VOLJET

Model 255 Shehana = SX-255 light helicopter with Allison 250-C20B turboshaft engine (1982)
Model 276 mid-1992 design to investigate the possibilities of using the pressure-jet principle in an attack helicopter
Model 280 four/five seat light helicopter
Model 281 ultra-heavy lift helicopter of the pressure-jet configuration
Model 325 Jetaire developed from Model 280
Model 421 four-seat helicopter


PHOENIX HELIGYRO

Model 585 air pressure jet copter (= Air-Jet Rotor Helicopter)
PH200 single-seat prototype of PH-200-PJ, developed from Model 585
PH200-PJ two-seat helicopter/kitbuilt


Other unidentified designations

XH-10?
XH-20?



* also seen as Convert-A-Plane, Convertoplane and XNH-5
** according to http://www.rotorspot.nl/n-11.htm the VG-1 used to be an SNCASO 1221S Djinn

My dear Stargazer,




you forget the S11,it was a compound helicopter project.

Stéphane: the 1934 Nagler Helicogyro was single-seat craft that could operate as a helicopter or as an autogyro. In the later mode, the 2-bladed rotor freewheeled while the 90 hp Pobjoy drove a pusher propeller. Torque was to be counter-acted by the slotted tailplane.

The Helicogyro was testing in Britain in 1937 but considered to complex for production.

Thanks hesham for the S.11 designation (any pic or info?) and especially Apophenia for documenting the Helicogyro!

Sorry my dear Stargazer,


no more info or picture.

Jane's 1974-75 (p402) tells about a four/five-seat compound helicopter - nothing more :-\ .

That's right my dear Boxkite,and I think it was a misprint,and I suggest if they
meant Model-411.
