Entwicklung
In 1955, Hughes Tool Company's Aircraft Division carried out a market survey showing that there was a demand for a low-cost, lightweight, two-seat helicopter. The division began building the Model 269 in September 1955. The prototype flew on 2 October 1956.The Hughes 269 was designed with a fully articulated, three-blade main rotor designed by Drago Jovanovich, and a two-blade tail rotor. It also has shock absorber-damped, skid-type landing gear. The flight controls are directly linked to the swashplate of the helicopter so there are no hydraulic systems in the 269. There are generally two sets of controls.
In 1986, Schweizer acquired all rights to the helicopter from McDonnell Douglas, which had purchased Hughes Helicopters in 1984. After Schweizer acquired the FAA Type Certificate, the helicopter was known as the Schweizer 300C. The basic design remained unchanged over the years, despite Schweizer making over 250 minor improvements.
Der Hughes
TH-55 Osage war ein kolbenbetriebener leichter Trainingshubschrauber, der
für die US Army hergestellt wurde. Es wurde auch als die Modell 269-Familie
von leichten Hubschraubern produziert, von denen
einige als Modell 300 vermarktet wurden. Das Modell 300C wurde von Schweizer
nach 1983 hergestellt und weiterentwickelt.
Im Jahr 1955 führte die Flugzeugabteilung der Hughes Tool Company eine
Marktstudie durch, die zeigte, dass ein kostengünstiger, leichter
zweisitziger Hubschrauber
gefragt war. Die Abteilung begann im September 1955 mit dem Bau des Modells
269. Der Prototyp flog am 2. Oktober 1956.Der Hughes 269 wurde mit einem
vollgelenkigen Dreiblatt-Hauptrotor von Drago Jovanovich und einem
Zweiblatt-Heckrotor konstruiert. Es hat ein Stoßdämpfer-gedämpftes,
kufenartiges Fahrwerk. Die Flugsteuerung ist direkt mit der Taumelscheibe
des Hubschraubers verbunden, so dass es in der 269 keine hydraulischen
Systeme gibt. Es gibt im Allgemeinen Doppelsteuerungen.
1986 erwarb Schweizer die Rechte an dem Helikopter von McDonnell Douglas,
die 1984 Hughes Helicopters gekauft hatte. Nachdem Schweizer das FAA Type
Certificate erworben hatte, war der Helikopter als Schweizer 300C bekannt.
Das Grunddesign blieb über die Jahre unverändert, obwohl Schweizer über 250
kleinere Verbesserungen vorgenommen hat.
