Abstract:

Background The buoyancy of CF jet aircrew LPSV is unknown and may not provide the minimum 35 lbs that is required. The buoyant force of the British MK 30 LCX is also unknown however, this flotation device utilizes a large bladder and may replace the LPSV. Aim The aim of this experiment was to calculate and compare the buoyant force of the CF LPSV and the British MK 30 LCX. Methods Bladders were inflated using either a 35g or a 45g CO2 canister. A Chatillon spring scale was used to measure the buoyant force following submersion. Results The LPSV and MK 30 LCX attained buoyant forces of 41 and 42 lbs respectively following inflation using a 35g CO2 canister, and 45 and 53 lbs respectively following inflation using a 45g CO2 canister. Conclusion In all trials, both flotation devices produced buoyant forces greater that 35 lbs. The British MK 30 LCX produced larger buoyancy forces
