Lightweight Autonomous Dropwindsonde System for Unmanned Aircraft

气象气候中的许多突出问题 研究将大大受益于可用的 廉价的现场大气测量，特别是 在地球仪的偏远地区，例如在海洋上， 传统的测量系统很少或不存在。 的 国家大气研究中心（NCAR）开发了一种 轻型数字下投式探空仪系列和Aurora Flight 科学公司开发了一种低成本的无人科学 研究飞机（USRA）称为珀尔修斯。 本SBIR的目标 该项目是将数字下投式探空仪与 USRA将生产一种灵活、低成本的系统， 大气测量 在第一阶段，校长 调查人员将为NCAR制造一个分配器 把它安装在极光英仙座上 概念飞机。 分配器的概念将作为测试的一部分， 1991年初英仙座工程飞行试验的照片 接收器 和数据处理装置将在 基于. 在第二阶段，专门的机载数据收集和 将开发加工系统。

Many outstanding problems in meteorology and climate research would benefit greatly from the availability of inexpensive in-situ measurements of the atmosphere, particularly in remote regions of the globe such as over the oceans where conventional measurement systems are few or non-existent. The National Center for Atmospheric Research (NCAR) has developed a family of lightweight digital dropwindsondes, and Aurora Flight Sciences Corporation has developed a low-cost Unmanned Scientific Research Aircraft (USRA) called Perseus. The goal of this SBIR project is to combine the digital dropwindsonde with the with the USRA to produce a flexible, low-cost system for providing in-situ atmospheric measurements. During Phase I, the principal investigators will fabricate a dispenser for the NCAR dropwindsondes and install it on the Aurora Perseus proof-of- concept aircraft. The dispenser concept will be tested as part of Perseus' engineering flight tests in early 1991. The receiver and data processing unit for this demonstration will be ground based. During Phase II, a dedicated airborne data collection and processing system will be developed.
