Yesterday morning, the Merlin LSA wing was subjected to its “load to failure” test. The wing passed the “limit load” (what the airplane must handle) and “ultimate load” (1.5 times limit load – the ASTM required safety margin) tests in all loading conditions with flying colors. The wing was then tested well beyond the required safety margin.
Bottom line: This wing is strong! The horizontal stabilizer and control surfaces have already been tested with similar results. This test is a major milestone in Merlin development. Stay tuned for more updates as we move forward with Merlin testing!
