LP/SV bladder buoyancy test comparison / by Bill Martell and Ryan Wolter.: D68-5/116-2011E-PDF
Background: The buoyancy of CF jet aircrew LP/SV 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 LP/SV. Aim: The aim of this experiment was to calculate and compare the buoyant force of the CF LP/SV 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 LP/SV 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.
