Abstract
In a world of modern technology millions of people worldwide travel daily by air to destinations both near and far.
In North America, as well as various European locations including the Scandinavian countries, winter weather is both an annual cycle and a challenging threat.
Each year dozens of airports throughout the Northern Hemisphere millions of litres of de-icing fluids mainly Glycol of various types, are used in order to de-ice aircraft for safe and successful take-off.
This de-icing fluid is very expensive and somewhat less than environmentally friendly. Various airport commissions and environmental groups have on numerous occasions voiced concern regarding de-icing fluid runoffs into the soil and nearby streams and rivers. And eventually even into water tables, etc.
For many years aircraft have had their interiors heated before the boarding of passengers via a large hot air duct being run from a portable heater unit of several types and designs.
After testing various mechanical possibilities in and around various aircraft at major airports my co-inventor and I, being employees of a major airline, have come up with a rather unique adaptation.
An adapter type unit when connected to an existing heater or heaters which were sole designed to supply heat to the interior of parked aircraft.
This adapter when connected to the existing heater unit can produce enough heat and hot air to melt frost, ice, or snow from the propellers of an aircraft and at the same time blow it away. This invention in future will find use in de-icing other aircraft surfaces, such as wings, tail, landing gears, fuselages, and thawing frozen jet engines.
The main purpose of this apparatus is to successfully reduce the gross use of glycol and other type fluids which can be harmful to the environment.

Description
SPECIFICATIONS:
Using already produced technology this new and innovative specially designed adapter hose nozzle can when properly fitted ( Fig 2 ) allow hot air flow to be used for a very practical purpose.
Instead of spraying jet propulsion systems with de-icing sprays due to icing problems on tarmacs and airport runways, this heater flow system can be utilizes to incorporate environmentally friendly and inexpensive generated heat. The adapter nozzle and hose will merely melt ice and snow from the aircraft's propellers and allow the ice in turn to be blown away as actual water, see ( Figs 3, 4 ).
Testing of the heater application with prototype nozzles and hoses have proven successful in de-icing landing gears and thawing frozen engines ( Fig 5 ).
Future applications are being considered, including such areas of the aircraft as wings, tail sections, and possibly the aircraft's fuselage.
The newly manufactured hose and nozzle will be so designed as to fit most portable heaters now in existence ( Fig 1 ). The purpose of this nozzle/hose application is to address the environmental problems associated with present day de-icing sprays and to save airlines money from the expensive costs for de-icing fluids.
This invention consists of approximately ten (10) feet of specially designed hose six (6) inches in diameter. Attached to the end is a specially designed nozzle tapered down to an oval four (4) inch opening with two designed handles for holding onto and directing the flow of hot air see ( Fig 7 ). The tapered feature gives the nozzle more accuracy for specific areas and increases the outflow of hot air. The opposite end of the hose has an attachment designed to fit any existing heater units designed and built for aircraft interior heating. This attachment can also be removed so as the hose can be connected directly to the heater unit with the aid of a reducing device as seen in attached drawings ( Fig 6 ).
Material for this new hose and adapter will consist off various types of plastics, rubber, aluminum, and polyurathane.
