Dirigible for towing an object on the ground or under the water e.g. a sonar buoy or land mine clearing tool has nacelle fixed under the balloon with motors adjustably oriented about a vertical axis for pulling a immersed sonar via a cable

摘要

The dirigible has nacelle (2) fixed under the balloon-like part (1), this nacelle having motors adjustably oriented about a vertical axis for pulling a immersed sonar via a cable in any intended direction regardless of the wind direction. The nacelle has two traction motors fixed along an adjustable transversal axis, for ensuring the necessary force for piloting the dirigible. It can contain a reel for the cable and a cradle to receive the sonar when the reel is retracted, for allowing it to fly faster.
