Stojan高壓釜試驗儀

SV-2 (Stojan Vessel®) 用於測試固態火箭推進劑的燃燒速率與壓力關係，既省時又省錢。 單次試驗就足以繪製整個壓力範圍的燃燒率，與 Strand Burner 相比，Stojan高壓釜試驗儀是一種簡單而安全的裝置，基於更先進的數學計算程序，計算一次爆炸的特性。

這項產品是由Petr Stojan 博士發明暨開發了這項程序，使用他的儀器進行測量成為捷克共和國火箭推進劑的標準測試方法。

應用

 

SV-2 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：

• 添加劑（緩和劑、催化劑、黏合劑、氧化劑等）的影響。
• 與初始溫度的關係。
• 預測老化試驗後不穩定的燃燒或爆炸危險。
   

選配附件 OZM Research 還可以提供 SV-2 和 LTRM 儀器樣品製備和調節所需的所有設備 和程序（液壓機、沖壓工具、鑄造模具、切割機、切割工具、恒溫箱 …等）。 亦可提供實驗室用火箭發動機，用於驗證測量結果。 優勢和特點 操作快速安全，完全遠端控制。 不銹鋼的高壓釜設計，便於清潔複合固體推進劑殘留物。 工作压力最高達500 bar。 透過燃燒固體推進劑進行 750 bar 耐壓測試。 配備內建冷凝器的緊湊型移動式台車。

The SV-2 (Stojan Vessel®) is designed for the time and cost saving determination of the burning rate vs. pressure depen- dencies of solid rocket propellants. A single shot is sufficient for plotting burning rates in the whole pressure range.
The measurement using Stojan Vessel is primarily based on the advanced procedure for the determination of the burning rate of solid rocket propellants. In comparison with the Strand Burner, Stojan Vessel is a simple and safe instrument based on the more advanced mathematical procedure for calculation of ballistic properties taken from a single shot only. This procedure was invented and developed by Dr. Petr Stojan and the measurement using his instrument became the standard testing method for rocket propellants in the Czech Republic.

APPLICATIONS

The SV-2 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.)
• Dependence on initial temperature
• Prediction of unstable burning or explosion hazards after ageing tests

OPTIONAL ACCESSORIES OZM Research can also supply all the equipment and procedures necessaryfor sample preparation and conditioning of both the SV-2 and the LTRM instruments (hydraulic press, pressing tools, molds for casting, cuttingmachines, cutting tools, temperature chambers, etc.). Laboratory sub-scale rocket motor available for validation of measurement.   ADVANTAGES & FEATURES Quick and safe operation, fully remote controlled Design of the stainless steel closed vessel allows for easy cleaning of composite propellants residues Workingpressure up to 500 bar 750 bar proof pressure tested by burning solid propellants Compact mobile working trolley with in-built chiller
