ARCTIC KIT FOR USE WITH AIRCRAFT WIRE DISPENSER SET AN/ATE-1 DEVELOPMENT PHASE.

Various modifications of the Arctic Door Closure Kit for use with Aircraft Wire Dispenser ANATE-1 were considered for the purposes of 1 Overcoming the deficiencies noted during rain test and vibration test of the prototype. 2 Incorporating suggestions for improvement noted in Report No. 2 and Report No. 4 of prototype contract, and in Technical Report ECOM-6008. 3 Eliminating requirements for installation on CH-21, CH-34, and UH-1A helicopters, and adding requirements for installation UH-1D helicopter. 4 Complying with human factors engineering requirements as they affect installation, operation, maintenance, repair, and stowage of the Arctic Kit. 5 Achieving an economical design which can be manufactured in production quantities with maximum ease and minimum cost consistent with performance requirements. Sketches are shown of the different possible methods of accomplishing the above objectives. The advantages and disadvantages of alternate methods are listed. A new survey of available materials for the curtain and seals was made, since the temperature range for instllation and operation of the Arctic Kit has been changed from -80F thru 160F for the prototype, to -65F thru 125F for the advanced development model, and also to determine if more suitable materials have become available since the survey was made for the prototype. From the different possible methods and materials investigated the most suitable are selected and recommended for the advanced development model Arctic Kit. Author
