;ABSTRACTs HN Is not used In practice as an explosive,, nevertheless.. it is of
!interest to ditermine its detonation characteristics in the liquid state* Measure-
meat of the detonation characteristics are frequently used in the studies of tho
hi pressures (hundreds of thousabdo of atmos-
equation of the state of gazes at 911
-pheres)',and at high teVeraturee (several thousand degrees)* In treating experi-
mental data one is involved vith multicomponeat systems since the majokty of
1,explosives consist of at least four types of atomse Consequently,, the explosio--'
products contain several types of moleculeso In this respect HNI differs frAwrobly!
i-from other explosives because one might expect that products of detonation of
-liquid HN All consist primarily of molecular nitrogen and hydrogen* The rates

ABSTRAC"I't Previous studies have mhown that the detonation velocity D in liquid- 1
and solid-explosive charges depeuds mainly on the power of the detonator. This
dependence was stuidlea using the high-speed photogrNhic camera IM-2. Sherpa
(5-40 um in diameter d and 50-4W us lonj) of.1KRU, tatryl, and h"toganwere
detonated with a week and a strong diatons. _r
tot. x GTA-Naci (som) squib
(d - 20 me, dmnsiW p - 1.0 &/". and D a 2000 st/see) was used as the weak distoostoft
i the saw siss squib of compacted tratyl (p - 1.62 &/cc, D - 6900 Wase) was used
as the troing detonator# The charge diameter dependence curves of the distouatiou
veloc14 (D vs. d) show that In all comes where the charges are detainated with
the weak detonator. then Is a certain charge dismater range within which low-
velocity Jotonation is stable, Its low-velocity detonation increased five 1200 to:

velocity also depends on the site of its particles, The upper limit of
which low-velocity detonation is stable varies with the explosive (%30 MM 1%)k
trotyl, %17 mm for hazogen, aud N20 = for tatryl with a partic-lo site of ~'LO-1.6 no.
The low-velocity detonation regime which is developed in totryl and hezogen
charges changes suddenly to a normal velocity reglain after a distance of about
2-4d of the char&*. In trotyl charges, the low-velocity detonation changes
slowly to a normal regime. In the explosive charges detonatnd with the strong
detonator, a stable normal velocity detonation regime to established at a short
distance from the initiation point and in the came of trotyl end hexagen, the
detonation propagates with an approximately constant velocity over the d tango
studied. In the cooo* of te'tryl, a stable detonation was observed only in charges
of a cftt-&W dUwotoor. Thus, In trotyl and hexogen charges, depending on the detonator
used, stable low-velocity or normal-volotity detonation regims are established In
a certain rangs of diameter*; andlin the case of totryl. a stable detonation
regime is established only In charges of a certain diameter regardless of the
detonator used, To explain the lov-volocity detonation Initiated by & weak
detonator, It to suggested that the amount of heat liberated during Initiation by
a weak detonator Is not sufficient to maintain tha combustioa Inside the charge
particles and so the combustion propagates on their surface. Oris. art. hani
