Design & Development
The L 72 was a single-engine biplane of conventional configuration with unstaggered wings of equal span. It was the first German commercial aircraft to incorporate leading edge slots and trailing edge flaps. The upper and lower wings were interchangable. They were of all metal construction with fabric covering. The thickened centre section of the upper wing contained the fuel tanks. The upper wing was carried on a tubular cabane and one set of 'N' formation interplane struts was provided with stream-lined wire bracing. The fuselage was built of welded steel tubing with diagonal wire bracing and was fabric covered. Aft of the pilot's cockpit was a cabin containng a conveyor-like device which could accept up to 16 parcels of newspapers weighing 10 kg. each. These could then be dropped, either by an attendant travelling in the cabin or by the pilot, an indicator in the cockpit indicating how many parcels had been dropped. A novel feature of the tail was the rudder and fin which were both pivoted in such a way that when the rudder was turned the fin also turned around a vertical axis thus providing a more powerful rudder control for a smaller angular movement

Famous quotes containing the words design and/or development:
“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,—some of its virus mingled with my blood.”
—Henry David Thoreau (1817–1862)
“Ultimately, it is the receiving of the child and hearing what he or she has to say that develops the child’s mind and personhood.... Parents who enter into a dialogue with their children, who draw out and respect their opinions, are more likely to have children whose intellectual and ethical development proceeds rapidly and surely.”
—Mary Field Belenky (20th century)
