摘要：<p>A thermal aircraft, such as a hot air load-carrying balloon (1) which includes a balloon envelope (2) having a deflation aperture (3) therein and a venting valve or operculum (16) designed to removably cover and seal the aperture and to be opened and/or closed rapidly so as to assist in the control of the balloon, forming both a deflation panel and a manoeuvring port for the balloon. The venting valve (16) is removably and releasably secured to the balloon envelope adjacent the periphery of the aperture (3), and means (17, 21, 23, 28) are provided for controllably and selectively positioning the valve in the aperture for open and closed dispositions thereof. Separate controls are provided firstly (17, 17a, 17b, 21) to extend the valve (16) to its maximum surface area, at which point it removably covers and seals the aperture and/or to allow controlled venting of hot air therefrom, and secondly (23, 28) to allow reefing of the valve (16) from the aperture (3) for rapid deflation of the envelope (2). This provides the pilot with a great deal of control over the flight of the balloon, especially during final landing procedures and especially during such procedures in gusty or windy conditions, contributing significantly to control and safety. <IMAGE></p>
