100 hp Mercedes
The following is from www.histaviation.com
The types Caspar-Theis CT 1, CT 2, CT 4, CT 5 are the same in structure and construction and only differ slightly from each other. The differences are the installation of 80 hp Mercedes in CT 1, 100 hp Mercedes for CT 2 and CT 5, 120 hp Mercedes for CT 4. Compared to the other types, the Type CT 4 has a common fuselage cutout for the driver and observer. The Type CT 5 is a school machine with school controls furnished. The calculation of the supporting deck etc. was carried out in accordance with the existing regulations and confirmed by load tests. The span of the upper deck is 11.5 m, that of the lower deck is 9 m and the surface depth above and below is 1.4 m. The upper deck is forward against the lower deck staggered and has a circular cutout above the passenger seat. The total wing area is 25 m2. The empty weight is 600 kg, the payload is 260 kg and that Flight weight 860 kg, the spec. Wing load therefore 34.4 kg. The machines are designed as single-handled double-deckers with normal tension. The lower decks are hinged to the hull. The upper decks are on the from Canopy-supported middle deck attached. The canopy has an N-shape and is made of teardrop-shaped steel tube. It is connected from the front and back by a cable Bottom edge of fuselage intercepted.
The stem consists of two struts and two diagonal crossover cables. The middle deck accommodates the supporting deck cooler in the middle, and to the side of this is a Drop tank installed. The wings are a normal two-spar design with fabric covering and cable crossing. The spars are made from solid to double T-shaped milled out according to cross section. After milling, the rear spars were covered with plywood on both sides. The rib construction consists of grooved belts Plywood bridges and wooden strips arranged in a truss-like manner. The ribs have the same profile from the inside almost all the way out, except for the end ribs decreasing profile. The end strip has a round shape and is hollow. The hull has four spars made of normal bulkhead construction and plywood paneling and ends in a horizontal cutting edge. The damping surface and the Like the wings, the keel surfaces also have normal wooden spars and rib construction. The spur is attached to a spur frame made of tubular steel and cushioned with elastic bands. The control surfaces and torsion flaps are made of tubular steel with fabric covering. Operating the elevation and windage control The rudder is carried out using cable pulls. The torsion flaps are controlled from the control shaft in the fuselage by means of cross levers, bumpers that run through the entire wing The levers attached to the aileron shafts are actuated.
The chassis consists of two V-struts, which are connected at the bottom by two auxiliary axles. The front and rear strut levels are crossed by steel cables. The main axis is suspended in elastic bands. The suspension travel is limited by an interception cable. The engine compartment is penetrated by the main tank behind it A sheet steel bulkhead is separated in a fire-safe manner.
