Bartos/Nobel BN-1 Phantom
The Bartos/Nobel BN-1 Phantom is an American, two-seat, mid-wing glider designed by Gene Bartos in the late 1960s.
Design and development
Bartos developed the BN-1 using the fuselage from a Laister-Kauffman TG-4 and designing new wings. The fuselage was highly modified to include an all-flying T-tail and new cockpit canopy. The wings have a greater span than the TG-4 using a NACA 44-series airfoil. The new wing uses top-surface spoilers in place of flaps. The new wing results in a glide ratio improved from 22:1 to 25:1.The fuselage is made from steel tube, while the wings are of wooden construction, all finished with doped aircraft fabric covering. The landing gear is a fixed monowheel, supplemented by a nose skid.
