Eliminating propeller injury through adaptation of military pump jet

描述（由申请人提供）：SBIR项目-第一阶段：泵喷射推进系统模块化适配器的可行性。可行性的目的是确定是否可以创建一系列适配器模块，使Pump Jet推进系统能够连接到美国大多数商业制造的舷外发动机上。Pump Jet是一种安全高效的轴向旁通流泵推进系统，用于消除螺旋桨撞击人和环境的可能性。它附着在舷外发动机的传动轴上。不幸的是，军方使用的舷外发动机仅占目前民用船只可用发动机的2%左右。不同制造商的规格阻止泵射流容易连接到大多数舷外电机。迄今为止，对于大多数正在使用的休闲船来说，还没有比传统的无保护螺旋桨更安全、更经济的替代品。Pump Jet的广泛使用将大大减少因娱乐和商业船只螺旋桨撞击造成的死亡和伤害。研究人员将结合现场调查，公布的组件规格，并对市场上98%的商业舷外机的电机组件进行测量，以编制相关组件规格的综合数据库。将对这些进行分析，以确定规格组，并确定创建“系列”适配器模块的可行性，这些模块将使pump Jets能够轻松且经济高效地安装到当今美国使用的大多数舷外电机上。SBIR项目-第一阶段：泵喷射推进系统模块化适配器的可行性。在美国，每年有60到100人死于摩托艇螺旋桨撞击。另有600至700人因舷外摩托艇螺旋桨撞击而严重致残，留下终生伤痕。该项目将确定是否可以创建一系列适配器模块，以便在没有活动部件暴露给用户的情况下使用摩托艇螺旋桨的安全替代品。

DESCRIPTION (provided by applicant): SBIR Project - Phase 1: The feasibility of modular adaptors for Pump Jet propulsion systems. The objective of this feasibility is to determine if a family of adaptor modules can be created to enable the Pump Jet propulsion system to be attached to the majority of commercially manufactured outboard motors in the US. The Pump Jet is a safe and highly efficient axial bypass flow pump propulsion system developed for the military to eliminate the possibility of propeller strike with people and the environment. It attaches to the drive shaft of an outboard motor. Unfortunately the outboard motors used by the military represent only about 2% of those currently available to civilian boaters. Differing manufacturer's specifications prevent Pump Jets from being readily attached to most outboard motors. To date, safer, cost effective alternatives to traditional unprotected propellers have not been available for the majority of recreational boats in use. Widespread use of the Pump Jet would dramatically reduce deaths and injuries due to propeller strike on recreational and commercial boats. Researchers will use combination of field surveys, published component specifications, and measurement of motor components for 98% of commercial outboards on the market to compile a comprehensive database of relevant component specifications. These will be analyzed to identify specification groups and determine the feasibility of creating a 'family' of adaptor modules that will enable Pumps Jets to be easily and cost effectively fitted to the majority of outboard motors in use in the US today. PROJECT SUMMARY SBIR Project - Phase 1: The feasibility of modular adaptors for Pump Jet propulsion systems. Between 60 and 100 people are killed by motorboat propeller strikes each year in the United States. Another 600 to 700 are horribly maimed and scarred for life as a result of outboard motor boat propeller strikes. This project will determine if a family of adaptor modules can be created to enable use of a safe alternative to motor boat propellers where no moving parts are exposed to the user.
