LP/SV bladder buoyancy test comparison [electronic resource] / by Bill Martell and Ryan Wolter. [Ottawa] : Defence Research and Development Canada, c2011. iv, 14 p. : figures. Technical Note ; 2011-116 "July 2011." Includes bibliographical references. 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. gccst Technical reports Life preserver Safety vest Wolter, Ryan. Defence R&D Canada.
