Disse nye "flyene" må være så lette som overhode mulig for å få max ut av batteriene. Derfor er det god grunn til å teste skrogkonstruksjonen for å komme frem til sertifiseringskriterier. Husk at sikkerheten for de ombordværende skal være den samme som eller bedre enn det som gjelder for kommersiell flyging i dag. Presset på produsentene, og de er det veldig mange av, øker etter hvert som tiden går. De bruker av investert kapital uten at de vet hva dette vil koste. (Red.)
NASA Crash Tests eVTOL
Mock-Up

NASA has crash-tested a version of an eVTOL
fuselage and the crumpled result will provide plenty of data on some NASA
innovations included in the mock-up. The composite structure was hoisted about
30 feet in the air and sent on an inclined trajectory to the concrete below in
a simulation of an emergency landing by an eVTOL. The test article was built by
NASA and was not a copy of any of the dozens of eVTOLs now under development.
There were six crash test dummies aboard and the roof was loaded up with weight
to simulate wings and engines. The structure did not hold up well.
Although the energy-absorbing floor and seats
appear to have functioned as designed, engineers were surprised the roof of the
passenger cabin collapsed with the weight of the simulated wing structure. The
simulated passengers in the back seats may have suffered some real damage. “Our
computational pretest models did a good job predicting the composite
deformation until overhead structural failure,” NASA spokesman Justin Littell
said. “However, the computational models did not predict the overall collapse
as seen in the test,” Little said in a statement. “The test was a great success
for the crash-worthiness team at Langley.”
