The Bloch MB.300 Pacific was a three-engine airliner made by the French manufacturer Societé des Avions Marcel Bloch in the 1930s. Since the prototype was not convincing, no further copies were built. Because of its size, the aircraft was nicknamed "La Grosse Julie".
history
In 1935, Air France commissioned the manufacturer Bloch to develop two new commercial aircraft for 16 and 30 passengers respectively. In addition to the twin-engine MB.220 , the design of the larger MB.300 was created. The manufacturer took over the wings and other components of the MB.210 bomber for both models .
The first flight of the MB.300 took place on November 15, 1935. The subsequent test flights made it clear that extensive changes were necessary. So the hull was lengthened and the wingspan was reduced. Based on the test results, the capacity had to be reduced to 24 passengers.
In 1937 Bloch's successor company SNCASE sold the revised prototype to the French government. Further tests were carried out in the following months. In January 1938, the aircraft entered service with Air France for a short time, before being sold to Spain.
Since SNCASE could not expect any further orders, the company discontinued the project and concentrated on the successor model MB.161 .
construction
The MB.300 was an all-metal aircraft designed as a low wing aircraft with retractable landing gear. The cross section of the fuselage formed a rounded rectangle. Initially, three double radial motors Gnôme-Rhône 14K with 750 kW each served as drive , which were later replaced by more powerful 14N .
The cabin was divided into three compartments, in which, in addition to a bar, 14 first and 16 second class seats were provided. The final version provided for three sections for eight passengers each, including a bar in the middle compartment. A maximum of four seats could be arranged per row. The cockpit crew consisted of two pilots, a radio operator and a navigator.
