RAMCOM-2 - RAM Mixer Contactless Monitoring

Falcon项目位于Westcott Venture Park，位于艾尔斯伯里附近的旧火箭研究机构，是目前英国仅有的三家制造固体燃料火箭和火箭推进剂的公司之一。以前我们采用常规的高剪切混合来将推进剂组分如铝粉、高氯酸铵、各种粘合剂和丁羟橡胶进行联合收割机混合;然而，Falcon在新的应用中采用了共振声混频（RAM），因为它具有许多优点。虽然RAM提供了许多好处，我们的问题是混合作用（其发生在夹紧到以容器和桌子的共振频率振动的桌子的封闭容器中）还没有完全理解。为了保持一致性，推进剂组分均匀分散至关重要，尤其是在组分可能具有不同尺寸和密度的情况下，如何实现这一点，更不用说其他添加剂对HTPB橡胶基的增塑作用尚不清楚。我们的目标是与NPL一起开发一种技术，使我们能够在动态混合过程中进行质量控制和优化新配方。

The Falcon Project based on Westcott Venture Park, the old Rocket Research Establishment near Aylesbury is one of only three companies who currently manufacture solid fuel rockets and rocket propellants in the UK. Previously we used conventional high shear mixing to combine the propellant components such as aluminium powder, ammonium perchlorate, various binders and HTPB rubber; However, Falcon is adopting Resonant Acoustic Mixing (RAM) for new applications because it has many advantages.Whilst RAM offers many benefits, our problem is that the mixing action (which takes place in a closed vessel clamped to a table which vibrates at the resonant frequency of the vessel and table) is not fully understood. For consistency, it's critical that the propellant constituents are uniformly dispersed, and how that takes place is particularly where the components can have different sizes and densities let alone the effect of other additions to plasticise the HTPB rubber base is unclear. Our objective is to develop a technique together with NPL to enable us to follow the dynamic mixing process whilst it's in progress both for quality control and optimisation of new formulations.
