Explosion of HMTD after 11 Months of Storage - Part 4
Взрыв ГМТД после 11 месяцев хранения - Часть 2
After 11 months had passed, I tested the second sample. The measured electrical resistance was 0.6 Ohm. I secured the cylinder in a retort stand, set up a protective shield, and placed an inverted tin can beneath the cylinder. To protect my hearing, I put on headphones and connected a 6-volt lead-acid battery to the contacts.

White smoke began to rise from the cylinder's stopper. At first, it escaped slowly, but then it shot upward in a strong jet. A short time later, a loud explosion followed, and the can was thrown aside. Because the headphones absorbed the sound, I could not tell at the moment whether the substance had detonated or whether the cylinder had merely been blown away by the jet thrust of the escaping gases.

On inspection, it became clear what had happened: the cylinder had been reduced to dust, and the bottom of the tin can had been torn out. The fragments had struck the base of the stand, leaving small craters. Several shards of the tin can were also scattered across the table and floor. Despite the violence of the explosion, the hot bridge wire remained intact.

Thus, the HMTD sample retained its ability to detonate even after 11 months of storage in contact with titanium wire. However, the explosion occurred with a noticeable delay-apparently because the layers of HMTD in direct contact with the titanium had already decomposed.



Взрыв ГМТД после 11 месяцев хранения - Часть 2
Когда прошло 11 месяцев, испытал второй образец. Измерил электрическое сопротивление, оно оказалось равным 0.6 Ом. Закрепил цилиндр в лабораторном штативе, установил защитный экран. Снизу под цилиндром поместил жестяную консервную банку, перевернутую дном вверх. Для защиты слуха надел наушники. Подключил к контактам 6 В свинцовый аккумулятор.

Над пробкой цилиндра появился белый дым, сначала он выделялся медленно, потом - ударил вверх сильной струей. Немного позже произошел сильный взрыв, банка улетела. Наушники поглотили звук, поэтому во время наблюдения я не знал, взорвалось ли вещество, или цилиндр просто улетел за счет реактивной тяги отходящих газов.

При осмотре обнаружил, что цилиндр разнесло в пыль, а у консервной банки разорвало дно. Осколки выбили маленькие "кратеры" в основании штатива. На столе и на полу нашел несколько осколков жестяной банки. Зато мостик накаливания (hot bridge wire) остался невредимым - несмотря на сильный взрыв.

Таким образом, вещество детонировало даже после 11 месяцев хранения и контакта с титановой проволокой. Однако взрыв произошел с заметной задержкой - по-видимому, слои ГМТД, которые непосредственно контактировали с титаном, подверглись разложению.
