產品介紹∣STOJAN鋼絞線燃燒器

特點
Features

SSB™ （STOJAN鋼絞線燃燒器）是Stojan高壓釜試驗儀® SV-2 儀器的改良型，用於測定固態火箭推進劑的燃燒速率。

SSB 允許使用兩種不同的測試程序進行實驗：恒定體積或準恒定壓力。

應用

SSB 用於研發、製造品質控製或雙基推進劑和複合固體火箭推進劑的在役監測。此方法可以高靈敏度和高可靠性地揭示影響受測推進劑彈道行為的以下因素：

不同添加劑（如 : 催化劑，減速劑，粘合劑，氧化劑等）對燃速的影響。
預測燃燒的不穩定性或爆炸危險。
燃速與推進劑初始溫度的相關性。

The SSB™ (Stojan Strand Burner) is an improved version of Stojan Vessel® SV-2 apparatus for the determination of the burning rate of solid rocket propellants. SSB allows to conduct experiments using two different testing procedures: in constant volume or at quasi-constant pressure.

APPLICATIONS

The SSB is used for research and development, for manufacturing quality control or in-service surveillance of both double-base and composite solid rocket propellants. The method can reveal with high sensitivity and reliability the following factors influencing ballistic behavior of the tested propellants:

Influence of additives (moderators, catalysts, binders, oxidizers etc.)
Prediction of unstable burning or explosion hazards after ageing tests
Dependence on initial temperature

ADVANTAGES & FEATURES
