Box 3

Scope and Contents

This files contains a request for NCAR support (superpressure balloons and telemetry) for a Middle Atmosphere Program (MAP) to study coupling of electrical phenomena in the middle atmosphere. A copy of NCAR's favorable review is included along with an estimate of costs. The name of this program was later changed to Electrical Properties of the Middle Atmosphere (EMA) and seven flights were made from Christchurch, New Zealand, in 1984.

Scope and Contents

Early correspondence describing the LLAMA (Long-Lived Atmospheric Monitoring Airship) concept and the specialized balloon material.

Scope and Contents

This file contains the complete history of a superpressure flight using composite materials (aluminized tedlar, Mylar, aluminum foil, and Kevlar fabric) and associated electronics to monitor balloon performance during a multi-year flight.

Scope and Contents

The RACOON concept permits the flight of large, low cost polyethylene balloons for several weeks at stratospheric altitudes without ballast. The balloon ascends each morning and descends at night. This movement of 15 to 20km in altitude provides an ideal platform for vertical soundings and sampling measurements in the stratosphere. The theory is described as well as the results of three globe-circling flights.

Scope and Contents This file contains papers and reports covering static and dynamic tests conducted by the FAA concerning the ingestion of the GHOST electronics package into a jet engine as well as balloon ingestion. GHOST package ingestion caused no fluctuation of engine performance either of a transient or steady state nature. Balloon ingestion caused a momentary, but non-hazardous reduction of engine power. During aircraft/balloon collision tests conducted at an altitude of 1500 feet and 300 knots...

Scope and Contents
