The titanium spar is filled with gas. If there was a crack in the spar the gas would escape, therefore tripping the pressure sensitive radiation shield. Releasing radiation that can be detected inside the helicopter.
Wireless systems aren’t used for opsec reasons.
- sandworm101 27d agoWireless arent used because they need power/wires and are less reliable than IBIS. Civilian versions of sikorsky helos use the same system.
- DoctorOetker 27d agocarrying a radiation source doesn't sound very opsec either to be honest...
- pixl97 27d agoWhy? It's not like it's gamma radiation.
- Johnny555 27d agoSince the radiation source is only exposed if it's indicating a potential main rotor crack, and it's not a very strong radiation source in the first place (so it's not like it allows long distance tracking), it seems like a minor risk -- if the radioactive capsule is exposed, the pilot is going to be returning to safe place to land. Beta particles typically only travel a few meters in air before they lose most of their energy.
