Eliminating propeller injury through adaptation of military pump jet

描述（由申请人提供）：SBIR项目-第1阶段：用于泵喷推进系统的模块化适配器的可行性。该可行性研究的目的是确定是否可以创建一系列适配器模块，以使泵喷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，为军方开发，以消除螺旋桨与人和环境碰撞的可能性。它连接在舷外发动机的驱动轴上。不幸的是，军方使用的舷外发动机仅占目前民用船的2%左右。不同的制造商的规格阻止泵射流容易地连接到大多数舷外发动机。到目前为止，对于大多数使用中的娱乐船来说，传统的无保护螺旋桨的更安全，更经济的替代品还没有。广泛使用的泵喷射将大大减少死亡和受伤，由于螺旋桨罢工的娱乐和商业船只。研究人员将结合实地调查、公布的部件规格以及对市场上98%的商用舷外机电机部件的测量，编制一个全面的相关部件规格数据库。这些将被分析，以确定规格组，并确定创建一个适配器模块的“家庭”的可行性，这将使泵喷射容易和成本有效地安装到大多数舷外马达在美国使用的今天。SBIR项目-第1阶段：泵喷推进系统模块化适配器的可行性。在美国，每年有60至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终身残废和伤痕累累。该项目将确定是否可以创建一系列适配器模块，以使用安全的替代摩托艇螺旋桨，其中没有移动部件暴露给用户。

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.
