The Hs129B-2, is an extremely interesting aircraft with many features. It is equipped with French production air-cooled engines Gnome-Rhone 14M, with automatically adjustable oil coolers and a constant speed screw (2750 rpm) with the possibility of manual direct control of the pitch of the screw and the mode of feathering. The airplane is equipped with flaps with a hydraulic smooth extending system, which includes a special metering cylinder for extending flaps right to intermediate take-off position.
In the cockpit, there is a folding armored seat for easy getting in the aircraft. The instruments for monitoring engine parameters are installed directly on engine cowls, outside the cabin. Front-firing weapons of the aircraft are installed in the central part of the fuselage, behind the cockpit, and fire through special channels along the sides of the cabin. Despite the tightness, the configuration of the cockpit canopy provides the pilot with excellent front-to-bottom visibility, which is extremely important for the attack aircraft. Collimator sight is installed very unusually - outside the canopy, in front of the armored windscreen, which is also unusual in itself because it has a curved shape with a multilayer structure. The "Revi C/12D mit Zieleinrichtung" gun sight is equipped with a special mechanical sighting device for level bombing at fixed altitudes and speeds; How to use it in detail is shown in the images below.
