|October 1, 1975
Summary
Canadian Forces (CF) aircraft ejections from 1967-1973 revealed helmet loss significantly increased minor head injuries. Improving helmet fit and wear methods can enhance retention and reduce injury risk.
Area of Science:
- Aviation Safety
- Aerospace Engineering
- Trauma Research
Background:
- Helmet retention and minor head injuries were significant issues during Canadian Forces (CF) aircraft ejections between 1967 and 1973.
- A total of 73 ejections involved Canadian-designed helmets.
Purpose of the Study:
- To analyze the relationship between helmet loss, airspeed, and Q force during aircraft ejections.
- To identify specific problems related to helmet fitting and wearing methods.
- To recommend guidelines for improving helmet retention.
Main Methods:
- Analysis of ejection data from 1967-1973.
- Correlation of helmet loss with airspeed and Q force.
- Examination of helmet fitting and wearing practices.
Main Results:
- Eighty-four percent of individuals who lost their helmets sustained minor head injuries.
- Thirty-eight percent of individuals who retained their helmets also sustained minor head injuries.
- Helmet loss was correlated with airspeed and Q force.
Conclusions:
- Helmet retention is critical for preventing minor head injuries in aircraft ejections.
- Improper helmet fitting and wearing contribute to helmet loss.
- Guidelines for enhancing helmet retention are recommended to improve aircrew safety.
