15、ion 072.1 0 1. SCOPE 1.1 Purpose, Policies and procedures established by MIL-Sm-1399 are mandatory. (This section defines the standard interface requirements for the design of systems, equipment, and structure which may be subjected to the blast generated by missile launches.) This section and the b

16、asic standard are to-be viewed as an integral single document. 1.2 Scope. This section addresses the interface characteristics of missile blast effects generated by the-launch of anti-air, anti-surface, anti-submarine, and point defense missiles from surface ship arm launchers, vertical launchers an

17、d box launchers. This section does not apply to submarine launched missiles. 13 Interfaces. The basic characteristics and constraint categories of this interface are shown symbolically on figure 1. The specific interface characteristics and constraints pertinent to this section are described in sect

18、ion 5. 1.4 Applicability, The criteria of this section are applicable to new ship acquisitions, modernizations, or conversions, and to systems and equipment intended for installation on board such ships. Systems and equipment intended for installation on board active fleet ships shall possess blast

19、resistance characteristics not less than those originally required for the ship in question. The criteria of this section apply only to ships designed for the installation of missiles. 2. APPLICABLE DOCUMENTS 2.1 Government publications. The following Government publications form a part of this docu

20、ment to the extent specified herein. Unless otherwise specified, the issues are those cited in the solicitation. PUBLICATIONS NAVAL SEA SYSTEiMS COMMAND (NAVSEA) S9072-AJ-MAN-OlO/BLAST PROT Design Guidance Manual for Gun and Missile Blast Protection (Application for copies should be addressed to Sta

In the event if a conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersed

22、es applicable laws and regulations unless a specific exemption has been obtained. 1 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-3. DEFINITIONS 3.1 Missile blast. Missile blast consists of a highly directional stream of erosive, high velocity, hig

23、h temperature combustion products resulting from the launch of a missile. In addition to gas products, the exhaust stream may contain a significant amount of liquid and solid particles of aluminum oxide, which is highly abrasive. 3.2 Direct blast areas. Direct blast areas are those areas exposed to

24、the direct line of impingement by the exhaust plume of the missile as it leaves its launcher. This applies for all potential missile launching orientations and fly-away patls. The direct blast area for rotating launchers will be based on the projected or actual launcher orientations allowed by the f

25、iring control cut-out cam. The direct blast area for vertical launch systems will include considerations for worst-case conditions of missile fly-away angles, ship motion and relative wind. The direct blast area for missiles in fixed canister and box launchers will consist of the area encompassed by

26、 a 45 degree conic projection on adjacent deckbulkhead areas unless a blast deflector is provided. 3.3 Reflected blast areas. Reflected blast areas are those areas outside the direct blast areas onto which the exhaust stream is deflected after impinging on a deck or bulkhead in the direct blast area

27、. The reflected blast area also includes areas where concentrations of exhaust gasses may collect. 3.4 Blast shields. Blast shields are structural plates used to protect an item from the missile exhaust stream in direct blast areas. 4. GENERAL REQUIREMENTS 4.1 General requirements. The specific inte

28、rface requirements and constraints established herein are mandatory and shall be adhered to by SYSCOMs. Project managers, contractors, and all others engaged in any aspect of shipboard design to which these requirements and constraints apply including systems/equipment design, production, and instal

29、lation. 5. DETAILED REQUIREMENTS 5.1 General considerations. The launch of ships missiles creates high localized temperatures and pressures, high energy erosive debris, smoke and toxic gases within the vicinity of the launcher. The nature of this environment may cause damage to nearby equipment and

30、structure, cause discomfort or a health hazard to crew members exposed to the gases, and may interfere with the performance of certain topside systems. Shipboard equipment exposed to missile blast are typically damaged by one or more of the following effects: a. Burning b. Surface erosion c. Paint b

31、listering 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-l399A(NAVY) Section 072.1 d. Gasket deterioration e. Warping f. Local structural failure of small fittings and attachments g. Coating by aluminum oxide Additionally, personnel statio

32、ned on weather decks may be subjected to exhaust gases or the gases may be ingested into interior spaces of the ship through ventilation intakes or other openings. Visual observation from the bridge and operation of line-of-sight systems such as laser designators and optical and infrared sensors wil

33、l be impaired by the exhaust cloud until it dissipates. - 5.2 Interface characteristics. The interface characteristics of the missile blast environment consist of the following elements: a. Temperature (see 5.2.1) b. Pressure (see 5.2.2) . c. Erosive debris (see 5.2.3) d. Smoke (see 5.2.4) e. Toxic

34、gases (see 5.2.5) These characteristics will be present on all ships with installed missile systems. 5.2.1 Temperature. The missile exhaust stream forms a long, narrow cone-shaped plume of high temperature gases. Temperatures at the core of the plume range from 1500 degrees Fahrenheit (“F) for a Tom

35、ahawk booster to 6000 “F for a Standard Missile 2 (SM2) booster. Gas temperatures over 1000 “F may be experienced up to 100 feet downstream of the SM2. These high temperatures exist, however, for only a very short period of time, generally under 1 second. 5.2.2 Pressure. The overpressure experienced

36、 by objects in a direct blast area results from the direct impingement of the supersonic stream of exhaust gases and particles. Pressures in the direct blast areas range from a few psi for the Tomahawk Mk 106 to 100 psi for the SM2 Mk 70, as an example. 5.23 Erosive debris. Liquid droplets and solid

37、 particles of aluminum oxide are present in the exhaust stream of those boosters which use aluminum as a constituent element. These droplets and particles are a major contributor to the heating and erosion effects of the missile exhaust stream. The solid particles cause an abrasive “sand blasting“ e

38、ffect, while the liquid droplets penetrate crevices and openings before solidifying on exposed surfaces. The SM family is the main concern with regard to erosive debris. 5.2.4 Smoke. Missile launch creates large clouds of smoke which may remain in the vicinity of the launch point from a few seconds

39、to a few minutes depending on the relative wind and weather conditions. While this cloud will not create any interference with radio wave systems, it will degrade the performance of sensors which operate in the lower electromagnetic spectrum, such 3 Provided by IHSNot for ResaleNo reproduction or ne

40、tworking permitted without license from IHS-,-,-MIL-STD-l399A(NAVY) Section 072.1 as laser designators, and optical and infrared devices. The infrared and visible light emission/ absorption characteristics of the launch cloud may pose a significant problem for these systems. Visual observation from

41、the bridge may also be impaired during ripple or salvo launches. 5.2.5 Toxic gases. The principal toxic gases contained in the launch cloud are hydrogen chloride (HCl), a colorless gas with an irritating pungent odor, and carbon monoxide (CO). Both gases are hazardous to crew members. HCl, in partic

42、ular, is an immediate danger to life, if in excess of allowable limits. Launch cloud and toxic gas concentration prediction methods are addressed in NAVSEA S9072-AJ-MAN-OlO/sLAST PROT. 5.3 Parameters. The missile blast parameters for application to any specific ship or equipment design must be devel

43、oped on a case basis from: a. Missile and booster type b. Launcher type c. Ship configuration d. Launcher train and elevation arcs if applicable e. Missile fly-away paths f. Smoke and toxic gas production The blast characteristics are determined from pressure-temperature curves specific to each miss

44、ile booster type which plot temperature and pressure as a function of axial and radial distance from the nozzle centerline, as shown on figures 2 and 3 for a Standard Missile Mk104 Dual Thrust Rocket Motor (DTRM). These curves, which when overlaid on a ship configuration drawing along with the envel

45、ope of potential missile fly-away paths, determine the local direct blast environment. The reflected blast areas are determined from an evaluation of the exhaust stream flow paths and areas of concentration of exhaust gases. Figure 4 shows the direct and reflected blast areas developed for a vertica

46、l launching system. The local blast pressures and temperatures, as shown on figures 5 and 6 for the forward vertical launching system on DDG 51, can be developed by hand for rough approximations, by computer program, or by actual shipboard measurements. Smoke and toxic gas spread must be estimated f

47、rom wind flow patterns around the ships superstructure and ship system arrangements, with consideration given to the potential concentration of smoke and gases in flow stagnation areas. 5.4 Areas of application. The direct and reflected blast areas will be designated by the Principal Development Act

48、ivity (PDA). 5.5 Interface constraints. Interface characteristics of the missile blast environment impose certain constraints on the design of ship structure, and on the design and installation of systems and equipment located in the designated blast areas. These constraints are described in 5.5.1 t
