Reference excerpt

The Rhein Flugzeugbau RW 3 Multoplan is a two-seat light pusher configuration aircraft that was produced in small numbers by Rhein Flugzeugbau GmbH between 1958 and 1961.

Design The prototype RW 3 Multoplan was designed by Hanno Fischer who founded Rhein-West-Flug Fischer in 1955 in order to test the aerodynamic principles that he propounded. These were first tested in the Fibo 2a light aircraft. This was followed by the first RW 3A Multoplan D-EJAS which was a tandem two-seat light aircraft of mixed construction with a high aspect ratio wing, retractable tricycle undercarriage and a T-tail. The 65 h.p. Porsche 678/0 engine was buried in the centre fuselage and drove a pusher propeller mounted in a vertical slot between the fin and rudder. The two occupants were provided with dual controls and were accommodated beneath a long blister canopy. A second RW 3A-V2 was built and tested.

Development and production

Fischer granted a production licence to Rhein Flugzeugbau GmbH (RFB) who built an initial batch of Multoplans at their factory at Krefeld-Uerdingen. The first production aircraft was flown on 8 February 1958 and this and all subsequent machines were designated RW 3.P75 to identify the Porsche 75 h.p. 678/4 engine which was fitted. RFB built a total of 22 Multoplans and abandoned a further three when production was discontinued in 1961. One further example was built by an amateur constructor. RFB also built two examples of a higher-powered version, the RW 3C-90 Passat and on these and all other RW 3s, they offered optional wingtip extension panels which enabled the Multoplan to be flown as a power-assisted sailplane. The extensions increased the span from 34 ft 9 ins to 50 ft 6 in.

Operational history The Multoplan was mainly operated by private pilot owners. Two examples remained operational on the German civil aircraft register in 2009 and two aircraft were exhibited in German aviation museums including D-EIFF displayed in the Deutsches Technikmuseum in the centre of Berlin.

RW.3-A two prototypes powered by 65 hp (48 kW) Porsche 678/0 engine. RW.3-A2 extended wing motor-glider with 15.40 m (50 ft 6 in) span wings. RW.3-A3 standard production light aircraft version with 10.4 m (34 ft) span wings and auxiliary fuel tanks at the wing-tips. RW.3-P75 22 production aircraft, and one amateur-built, powered by 75 hp (56 kW) Porsche 678/4 engine. RW.3-B glider version with wings extended to 15.40 m (50 ft 6 in). Aspect ratio 12. RW 3C-90 Passat two aircraft retrofitted with a 90 hp (67 kW) engine, then a 150 hp (112 kW) Lycoming O-320 with a Hartzell constant speed propeller.

Worked examples

Example 1 — a first encounter with Rhein Flugzeugbau RW 3 Multoplan

Start with the simplest possible case. Write down what Rhein Flugzeugbau RW 3 Multoplan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rhein Flugzeugbau RW 3 Multoplan before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rhein Flugzeugbau RW 3 Multoplan ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rhein Flugzeugbau RW 3 Multoplan

In research: Rhein Flugzeugbau RW 3 Multoplan appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Rhein Flugzeugbau RW 3 Multoplan in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Rhein Flugzeugbau RW 3 Multoplan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s German civil utility aircraft, Aircraft first flown in 1956, Aircraft with retractable tricycle landing gear, so understanding it makes those chapters shorter.
In everyday life: Look for Rhein Flugzeugbau RW 3 Multoplan outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
