इंग्रजी मध्ये SPECIFIC IMPULSE म्हणजे काय?
विशिष्ट प्रेरणा
रॉकेट आणि जेट इंजिनच्या कार्यक्षमतेचे वर्णन करण्याचा एक विशिष्ट प्रेरणा आहे. हे दर युनिट वेळेसाठी वापरलेल्या प्रणोदकांच्या संख्येसंबधीत शक्ती दर्शवते. प्रणोदक च्या "रक्कम" वस्तुमान दृष्टीने दिले जाते तर, नंतर विशिष्ट प्रेरणा गती एकके आहे जर ते वस्तूंमध्ये दिलेले असेल तर विशिष्ट प्रेरणात वेळांची एकके असतात. विशिष्ट आवेग च्या दोन आवृत्त्यांमधील रूपांतर कायम आहे. विशिष्ट प्रेरणा जितकी जास्त असते, तितके कमी करण्यासाठी प्रणोदक प्रवाह दर कमी होते आणि रॉकेटच्या बाबतीत तीनीओल्कोव्ह्स्की रॉकेट समीकरणासाठी दिलेल्या डेल्टा-व्हीसाठी कमी प्रणोदक आवश्यक असतो. वास्तविक एक्झॉस्ट वेग हे एक्झॉस्ट जेटची सरासरी गती आहे कारण ते वाहन सोडते. प्रभावी एक्झॉस्ट वेग म्हणजे एक्झॉस्ट वेग आहे जो व्हॅक्यूममध्ये समान जोर देण्याची आवश्यकता असेल. हे दोन्ही व्हॅक्यूममध्ये काम करणाऱ्या आदर्श रॉकेटसाठी सारखेच आहेत, परंतु वायु-श्वास घेणे जेट इंजिनसाठी ते पूर्णपणे वेगळं असतं ज्यामुळे हवेचा वेग वाढून अतिरिक्त जोर मिळतो. विशिष्ट आवेग आणि प्रभावी विल्हेवाट वेग प्रमाणित आहेत.
इंग्रजी शब्दकोशातील specific impulse व्याख्या
शब्दकोशमध्ये विशिष्ट प्रेरणाची परिभाषा म्हणजे रॉकेट इंजिनद्वारे इंधन खपराच्या उत्पादनातील उत्पादनाची गुणोत्तर. हे वेळेचे एकक आहे आणि प्रणोदकांचे एकक वजन एक युनिट तयार करण्यासाठी वापरले असल्यास त्या कालावधीची लांबी सतत जोरदार
