Pagination or Media Count:
The object of the invention is a method of testing actual specimens and panels of airplane skin for vibration resistance in a shell with a propeller-engine unit. The tested parts and the panels of the airplane skin are arranged in rows in ring fashion on frames, fastened on the walls of the channel of a shell at a given distance from the ends of the blades and are subjected to the action of vibration from the propeller. The vibration stress is measured by strain gages fastened on elements of the skin and connected by screened wire with the measuring equipment.
