Downloaded from https://www.everyspec.com MIL-STD-810D 19 July 1983 TABLE 514.3-VI. ~. ~ , - Continued DEFINITIONS q . maximum captive flight dynamic pressure in lbs/ft2.

(See note 1) p = average store weight density in lbs/ft3 (total weight -+ total volume) I t = 100al store average skin thickness where R is measured - inches R = one-half the average.of the major and minor diameters (inches) fOr a store with an elliptical cross-section (for cylindrical sections use local geometry; for conical seotions use smallest fl calculated using geometry within one foot of equipment mounting point; for cast irregular shaped cross-section, R shall be one-half the longest inscribed chord; for monocoque irregular oross-section, f1 300 Hz) NOTES 1. For endurance test, q = 1200 psf or maximum q, whichever is less. 2.

Free fall stores with tail fins, use fl = 125 Hz; f2 = 105(t/R2) + 1000 Hz. 3. For general-use fuzee which can be used in several storea; use W1 = 0.04g2/Hz; W2 = 0.3.g2/Hz; fl = 100 Iiz; f2 = 1000 Hz. 4. Acceptance range for parameter values: 40 ~ P S150 ,0.001 :t/R2 $0.02 - or if calculated values fall outside these limits, uae these limit values. 5. For circular and elliptical cross-sections. 6. 500 H Z for all other croSS-.seCtiOIIS. 7. If f. ?1200 Hz is calculated, use 2000 Hz. t43THOD514.3. 19 July 1983 514.3-48
