Nomenclature of composite solid propellant and charge 復合固體推進劑及裝藥術語

When liquid propellants are used the fuel and oxidize are fed under pressure to one or more combustion chambers and expanded to atmosphere through convergent-divergent nozzles . 當使用液體推進劑時,在壓力作用下,燃料和氧化劑輸送到一個或幾個燃燒室中,并通過收斂-打散噴管,排到大氣中。

The mechanical properties of improved double-base propellants enabled one to envisage grain geometrics with large combustion areas and consequently high thrusts . 經過改進的雙基推進劑的機械性能使我們能夠指望獲得大燃燒面的藥柱幾何形狀,從而得到大推力。

The above discussion on first-stage propellant slosh effects is based on the saturn vehicles, which use kerosene for fuel and lox for oxidizer . 上面對于第一級推進劑晃動影響的討論,是建立在“土星”飛行器的基礎上,它是采用煤油做燃燒劑,液氧做氧化劑。

To appreciate the unsteady environment existing in liquid propellant rocket chambers it is necessary that the steady state be well understood . 為了分析液體推進劑火箭發動機燃燒室中存在的非穩態環境,必須很好地了解穩態狀態。

The dynamic aspects of the combustion process are determined primarily by the injection pattern, the propellant combination, and the operating conditions . 燃燒過程的動力特性主要由噴射型式,推進劑組合及工作條件來確定。

The time lag can be envisioned as the time required for the liquid propellants to travel from the injector to an effective combustion “front. “ 可以把遲滯想象為液體推進劑從噴注器運行到有效燃燒“鋒”所需的時間。

We shall try by means of a highly simplified development to expose certain advantages and disadvantages of solid propellant rocket systems . 我們想通過相當簡單的推導來試圖闡明固體推進劑火箭系統的某些優缺點。

The propellants are acceptable for military purposes as relates to surveillance, electrostatic sensitivity and friction sensitivity . 就監視安定度,靜電感度和摩擦感度而言,這些推進劑是可作為軍用的。

The application of a pressure difference across an injector does not cause an immediate velocity response of the liquid propellant . 經過噴注器的壓降發生變化時并不馬上引起液體推進劑速度變化。

Sampling of propellants under typical operating conditions may be necessary to obtain valid capacitance information . 為了獲得有效的容量資料,在典型的工作條件下對推進劑取樣是很必要的。

It is difficult to separate the effects on stability of the propellant properties from those of the injection scheme . 要把推進劑性質對穩定性的影響與噴射型式的影響分開是困難的。

In this domain, flames are observed to move about on the surface of the propellant in a manner that is too irregular . 在這一區間內,火焰在推進劑表面上的運動方式是如此的不規律。

In using eq. 3-1 of course one first identifies the fuel molecules and the oxidizer molecules of the propellant . 當然,應用式(3-1)時首先要辨明推進劑的燃燒分子及氧化劑分子。

Solid propellant engine systems are basically less flexible in operation than liquid or hybrid propellant systems . 固體推進劑發動機系統的可調性基本上比液體或混合型的要差。
