A week article today reported S-97 program manager statement that flight testing is being halted again for another 9 to 12 weeks. Reason is to wait for more hours to be accumulated on the gearbox test stand units.
I recall reading somewhere a comment from Sikorsky saying with the S-97 they wanted to accumulate a certain number of hours of drivetrain bench test for each hour of planned flight test. Seems reasonable given the relative complexity of the drivetrain and that it is an all new design. Being internally funded there are no contract schedule milestones to meet, and any flight test failures will reflect poorly on Sikorsky's JMR-TD effort which relies on the same technology. So Sikorsky has very good reason for taking their time getting everything right before continuing with S-97 flight testing.
