NAGLER HELICOPTER
XNH-1Heliglider strap-on' rotorcraft to cross rivers or other obstacles with two solid rockets at the tips of the rotor (1952) XNH-2Heligyro 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 130Convertocraft* 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 141Vertigyro (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 193Honcho (Honcho 100) one-place helicopter with AiResearch 85-90 gas turbine feeding compressed air to the rotor (1972) [N1750Z] Model 200Yellow 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

VOLJET
Model 255Shehana = 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 325Jetaire developed from Model 280 Model 421 four-seat helicopter
PHOENIX HELIGYRO

"The VG-1 used to be an SNCASO 1221S Djinn"". The only part of the Djinn used in the VG-1 was the rotor system, adapted to be driven by a piston engine/compressor combination. The VG-1 (registered N5395Z) used a Piper PA-22 Tri-Pacer fuselage and u/c.
