Design the corrosion control hangar to provide space and equipment for the

15、corrosion control processing of aircraft. This corrosion control process can be performed at either a depot level or organizational and intermediate (O/I) level facility as defined in NAVAIR Technical Manual NA01-1A-509, Aircraft Weapons Systems Cleaning and Corrosion Control. Base facilities design

16、ed for depot level maintenance on de-paint/re-paint of the entire aircraft. Base facilities designed for O/I level maintenance on repair of damaged paint systems and de-paint/repaint of components only. This does not include de-painting by plastic media blasting (PMB) equipment. Functions performed

17、in the corrosion control hangar include: a. deicing, b. limited detergent washing and rinsing, c. paint stripping, d. corrosion removal, e. protective coating application and painting, and f. finish curing and drying. Refer to NAVAIR Technical Manual NA01-1A-509 for detailed functions performed in t

18、his facility. 4 For Air Force Facilities, the minimum facility requirements to support unit/base level corrosion control functions are an environmentally controlled area to wash aircraft and hangar space for corrosion treating, corrosion repairing, paint stripping and performing maintenance painting

19、 on entire aircraft. Space must also be provided for the Corrosion Control Shop, which includes a preparation and paint application area for aircraft components and support equipment; paint mixing area; tool and equipment storage; paint storage; personnel hygiene facilities and administrative areas.

20、 /4/ 2-2 LOCATION. Locate the corrosion control hangar in proximity to the maintenance hangars and as close as possible to an aircraft washrack. Access between the corrosion control hangar, the maintenance hangar, and the aircraft washrack is required. Consider the prevailing wind in orienting the b

21、uilding in relation to aprons, taxiways, and parking, to avoid exhaust air dispersal over areas affected by solvent fumes 4and to avoid recirculation into the ventilation system intakes./4/ Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-UFC 4-211-02

22、NF 10 January 2005 Including Change 4, 1 April 2010 4 Care must also be taken to site the hangar in accordance with the requirements of NAVFAC P-80.3 and UFC 3-260-01, Airfield and Heliport Planning and Design. It should not be sited within any runway safety zone or in a location where it might exte

23、nd into any imaginary surface. 2-3 ARCHITECTURAL AND STRUCTURAL REQUIREMENTS. 4 For Navy Projects,/4/ there are two types of depot level corrosion control hangars. a. Type A corrosion control hangars are designed for carrier aircraft and other small aircraft. b. Type B corrosion control hangars are

24、designed for land-based transport or patrol aircraft. Because both construction and operating costs increase as the volume of the hangar bay increases, design depot level corrosion control hangars for aircraft larger than those accommodated by the Type B hangar and O/I level corrosion control hangar

25、s around the specific dimensions of the aircraft concerned. Aircraft dimensions can be found using the Aircraft Characteristics Database at http:/ With the exception of the following special requirements, design the corrosion control hangar using the general architectural and structural requirements

26、 for maintenance hangars set forth in UFC 4-211-01N. The size of the various aircraft scheduled to use the facility will determine the hangar bay dimensions. Size the bay to accommodate fixed-wing aircraft with wings unfolded, and helicopters and V-22 with rotors in place and unfolded unless it has

27、been determined that aircraft surfaces are accessible with the wings/rotors folded. The following minimum clearances are required to allow proper access for work platforms and to minimize paint overspray on hangar walls and ceilings: (1) Top of aircraft (vertical fin, radome, rotor head, tail rotor)

28、 to underside of ceiling - 1.6 m (5 ft); (2) Nose of aircraft to hangar door - 3.1 m (10 ft); (3) Tail of aircraft or tail rotor to exhaust target wall - 3.1 m (10 ft); and (4) Horizontal and vertical clearance from aircraft to open front door - 1.6 m (5 ft). In addition to these clearances, the dep

The equation T = 1/5H defines this depth where H is t

30、he height of the aircraft at its highest point plus 1.6 m (5 ft). Note that the depth (T) does not include the thickness of the structure of the door or the filter media. Base the number of hangar bays for each site on an analysis of aircraft types, production schedules, hours required for each corr

31、osion control operation, and number of work shifts. Refer to 4 UFC 2-000-05N /4/ for criteria to develop the required quantity of bays. If the workload includes a mix of large and small aircraft, a moveable partition at the center of the bay can be used. Bays in which stripping, blasting, or grindin

32、g are done will be separate from spaces where painting is done. 4 For Air Force projects, determine the interior dimensions of the Corrosion Control facility, by using the dimensions of the largest aircraft that will occupy the facility plus an additional 3m (10 ft) on each side of aircraft to facil

33、itate maintenance stands, etc. Do not overlook tail heights, the height and width of door, openings, structural protuberances in facilities, and the turn radius of tow vehicles connected to aircraft. The chart listed below was derived from information in AFH 32-1084 and provides a means to determine

34、 minimum interior dimension requirements for an aircraft corrosion control hangar.

Provide a connection to the station Industrial Waste Treatment System or to a collectio

41、n tank from all drains. The corrosion control process generates large amounts of water that could potentially hold solid or liquid paint residue or other solvents and wastes. Provide space for work on composite helicopter rotor blades if applicable. An overhead bridge crane is not required in the ha

42、ngar bays. Locate utilities on the side walls. Use of utility pits in hangar floors is prohibited. Design for the aircraft fully loaded with fuel. 4 Shower Facilities: Provide shower facilities for persons engaged in the application of paints, coatings or other operations where contaminants may be h

43、armful. The shower area should be designed as “walk-through” allowing for the separation of clean and dirty environments. Showers shall have hot and cold running water feeding a common discharge line. Body soap or other cleaning agent convenient to the shower shall be provided along with individual

44、clean towels. Change Rooms: When employees are required to wear protective clothing, change rooms with storage facilities for street clothes and separate storage facilities for protective clothing shall be provided. Paint Mixing Rooms: All dispensing or transfer of flammable liquids from containers,

45、 mixing of flammable liquids, and filling of containers, including paint guns and pressure pots must be done only in an approved spray booth or mixing room. A separate paint mixing room will significantly reduce the Provided by IHSNot for ResaleNo reproduction or networking permitted without license

A properly designed and located paint mixing room will accommodate all equipment, cabinets, and tables associated with paint mixing and daily-use storage of paints and thinners, whic

47、h otherwise, would be housed within the confines of the paint booth. Installing prefabricated mixing booth is a simple method to incorporate a separate mixing area into a new or existing facility. The design requirements in Section 2 are generally applicable to paint mixing rooms. Additional require

48、ments are listed below: a. The size of the mixing room shall not exceed 150 ft2 (14m2). b. Must have continuous mechanical ventilation capable of providing not less than 1 cfm of air movement per ft2of floor area or 150 cfm, whichever is greater. c. Mixing rooms should be provided with a floor drain to make it possible to wash down spills. However, local installations must ensure that collection sumps are installed in the floor drain system and (or) that the wastewater treatment plant can process the spillage. If this is not the
