Today NASA conducted a crash test of a helicopter full of instrumented crash test dummies. Researchers at NASA’s Langley Research Center in Hampton dropped a 45-foot long helicopter fuselage from about 30 feet to test seat belts and other crash data.
It is unfortunate that this test was not done before the 2008 crash of the Sikorsky S-61N helicopter on the Iron Complex fire near Weaverville, California in which nine firefighters died. Seat belts was one of the problems identified in the NTSB’s investigation of that crash.
For today’s test the Navy provided the CH-46 Sea Knight helicopter fuselages, seats, crash test dummies and other experiments for the test. The Army contributed a litter experiment with a crash test dummy. The Federal Aviation Administration provided a side-facing specialized crash test dummy and part of the data acquisition system. Cobham Life Support-St. Petersburg, a division of CONAX Florida Corporation, also contributed an active restraint system for the cockpit.
Computers on the helicopter recorded more than 350 channels of data as the helicopter was swung by cables into a bed of soil. The helicopter hit the ground at about 30 miles per hour, which represents a severe but survivable condition.
A video of the test is below.
