Abstract:
A pipe of an apparatus has a first gas in a first space and a second gas in a second space. The first gas is in the amount to generate a buoyancy force that exceeds at least a gravity force to position the apparatus in a stationary state at a predetermined distance relative to a reference surface. A fixture is coupled to the apparatus to secure the apparatus in the stationary state relative to the ground without supporting the apparatus. The first gas is lighter than the second gas. The pipe is capable of creating a flow of the second gas.
Abstract:
Lighter-than-air systems, methods, and kits for obtaining aerial images are described. For example, various methods for determining planned ascent, drift, and/ or descent of a lighter-than-air system are described. In addition, various structural arrangements of lighter-than-air systems for accomplishing planned ascent, drift, and/or descent and obtaining aerial images are described.
Abstract:
In one example, a long endurance airship system includes a payload airship and a first logistics airship mechanically joined to the payload airship to form a first combined airship, the payload airship and the logistics airship having design capabilities differing by at least a factor of two with regard to at least one of: power generation capability, propulsion capability, endurance capability, and lift capability, in which the first combined airship is free flying, lighter-than-air, and configured to maintain stationkeeping for greater than 30 days. Illustrative methods for long endurance airship operations are also provided.
Abstract:
A buoyant gas based vehicle comprises a rectangular boat-shaped body made of carbon fiber material containing multiple of pre-shaped and prearranged inflatable air bags, a compressed buoyant gas storage container, reversible compressors or pumps, and a control system to regulate the amount of buoyant gas that will be pumped into the pre-shaped and pre-arranged balloons/ballasts to inflate or deflate them through preset programming to allow the entire body to become weightless. For traveling and transportation of human being and goods in a most economical way on account of infrastructure, cost of vehicles and fuel consumed by them, the buoyant gas is selected from Helium, Hydrogen, argon, Neon or Nitrogen etc., and the vehicle is made of light weight material such as plastic, aluminum, thermocol, pvc, polyurethane, polymeric and inflatable material etc. The vehicle is able to play on roads, travel in water and can fly in the sky.
Abstract:
La presente invención se refiere a un nuevo dirigible en el cual se instalan cámaras infrarrojas y radares para monitoreo de zonas urbanas y ductos de conducción de gas o derivados petrolíferos, para detección de fugas, así como para Ia revisión de los mismos; también para el transporte de refacciones y/o herramienta para Ia reparación de dichos ductos.
Abstract:
A heavier-than-air air vehicle (1), particularly a long endurance, solar powered, unmanned aerial vehicle (UAV) intended for "perpetual" flight within the stratosphere, is carried to its operational altitude suspended on a tether (14) from a helium balloon (16). The tether is attached at or towards a tip of the UAV's wing (3) so that it is carried in effectively a 90° banked attitude. At the desired altitude the UAV's powerplant is started and it flies on its tether in an upwardly-spiralling path relative to the balloon until a level or near level attitude is attained, when the tether is released and the UAV is permitted to assume free flight.
Abstract:
An airship system, comprising an airship (110), a base station (120), and at least three measurement points, wherein, when the airship (110) receiving an instruction from the base station (120) transmits ultrasonic wave, the measurement point units (S1 to S3) receive the ultrasonic wave to measure distances between the airship and the three measurement points and an MPU incorporated in the base station (120) calculates the position of the airship (110) and, according to the calculated position, the base station (120) transmits a navigation instruction to the airship (110) to control the route of the airship (110), whereby the operation of the airship by an operator can be eliminated, and the weight of loads mounted on the airship and the power consumption thereof can be reduced.
