This book was released on 1978 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The requirements for the Air Launched Balloon System (ALBS) development program and the highlights of that program, prior to the flight test phase, are presented. The rationale behind an ambitious ALBS parachute subsystem test flight series, using C-130 aircraft, at the National Parachute Test Range is given, along with the initial system configuration chosen for that series. The test-demonstrated inadequacy of the 32-ft drogue chute is documented. The successes achieved subsequently in flights with a 28-ft drogue chute (in combination with the 42-ft main chute) are described, both for tests employing a dummy balloon and for later tests in which a real balloon was used. Attempts at partial balloon inflation at the NPTR are discussed. The unsolved parachute coning problem is also described, along with tests aimed at its solution. Planning and preflight preparations for the January 1978 balloon drop test over the White Sands Missile Range are covered in considerable detail. The abortive launch of that flight is related and an analysis of the reasons for the flight failure is presented. Five (5) appendices are included with supporting calculations.

This book was released on 1976 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Air Launched Balloon System (ALBS) development history is traced and the circumstances leading up to planned ALBS flight tests are described, including a report on successful tests of the cryogenic storage subsystem. The theoretical performance of a candidate parachute development system--35-ft (10. 67 m) diameter ring sail drogue, 64-ft (19.51 m) diameter flat circular main chute--is mathematically analyzed using a number of stated assumptions. Contingency arrangements (e.g., use of ballast) and their impact are discussed. Data indicate that the ALBS mid-air deployment concepts require experimental proof-of-concept testing to ensure optimum component selection. Parachute subsystem verification tests planned for the autumn of 1976 at El Centro, Calif., are outlined along with plans for partial and complete ALBS system test drops from a carrier balloon in 1977 at White Sands Missile Range.

Book Synopsis Gas Replenishment Techniques for Use in High-altitude, Long-duration Scientific Balloon Flights by : Andrew S. Carten (Jr.)
Download or read book Gas Replenishment Techniques for Use in High-altitude, Long-duration Scientific Balloon Flights written by Andrew S. Carten (Jr.) and published by . This book was released on 1979 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers the theoretical advantages and practical ramifications of a proposed new technique for compensating for the daily loss of lift (gamma) experienced by long-duration high-altitude scientific balloon flights. This technique, 'Gas Replenishment', would transfer stored helium from an onboard dewar to the balloon, to replace gas lost due to temperature excursions. It would be a direct substitute for systems presently in use which drop ballast, that is, reduce system gross weight, to compensate for loss of lift. (With gas replenishment, lift is restored directly, with only a small change in system gross weight. A short summary of zero-pressure balloon flight theory is given at the start, to lead into the explanation of conventional ballast practices and computations. The ballast equations are then modified to apply to the gas replenishment technique. Calculations for typical constant-gamma flights are summarized for each method of loss compensation and the clear superiority of gas replenishment is demonstrated in the areas of gross system weight of launch, usable payload weight and anticipated flight duration. Basic equations are then developed for a more complicated model of the gas replenishment system in which the value of gamma varies from day to day. Computations using these formulas are summarized in tabular form. The final section of the report is given over to the design problems associated with the type of dewar and heat exchange equipment needed to implement the gas replenishment concept. (Author).

Download or read book The Air-Launched Balloon System (ALBS) Development Program written by Andrew S. Carten (Jr.) and published by . This book was released on 1981 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The circumstances leading to the second phase of the Air-Launched Balloon System Development Program are described, along with the governing design constraints. Individual component development efforts and system design modifications are described in turn: the procurement and testing of the new dewar, the qualification of the updated cryogenic unit, the redesign of the balloon/parachute interface, the solution of the extraction line recoil problem, and the development of a reliable cryogenic unit recovery system. The complicated command, control, and telemetry subsystem is also described in detail. The results of component tests and a system dress rehearsal system test are summarized. Preparations for two full-scale system tests conducted in 1981 are covered in considerable detail. The results of those tests are presented and the test data are analyzed. It is concluded that the system's air-launch and mid-air inflation techniques are acceptable. The balloon requires structural reinforcements, however, before the system can be said to be fully developed. (Author).
