Lift Coefficient
Hello All,
Along time ago, the 4 turboprop engined Breguet 941 had a blown high wing with 4 immense propellers(4m diameter each) for a half wing span of 9,88m. The 4 propellers were driven by one shaft so that an engine fail only made the 4 propellers turning more slowly & did not produce a yaw.
on my ATPL exam in 1972, there was a question about finding the CL coefficient for this STOL (Short Take Off & Landing) aircraft, the answer : CL = 8 !!
