50 n thrust correction engine for the "Luna-resurs" lunar module descent engine

Analytical Models for the Thrust of a Rotating Detonation Engine

Twomodels are proposed for rotating detonation engine performance. The first model is motivated bymodels of pulse detonation engine performance which are based on the pressure-time history within the detonation tube. The present work extends those ideas to treat rotating detonation engines with a control volume analysis that considers the forces within the combustion chamber. The key scaling pa...

Spelling Correction for Search Engine Queries

Search engines have become the primary means of accessing information on the Web. However, recent studies show misspelled words are very common in queries to these systems. When users misspell query, the results are incorrect or provide inconclusive information. In this work, we discuss the integration of a spelling correction component into tumba!, our community Web search engine. We present a...

Thrust Measurement of Single Tube Valve less Pulse Detonation Engine

In this paper we present the result of measurement of thrust of single tube valve less Pulse detonation engine. The thrust generated by the repetitive detonation from a 48 mm inner diameter ,60 mm outer diameter and 70 cm length (various lengths of tube varies from 20 cm to 100 cm in the steps of 20 cm interval ) detonation tube was measured using load cell. Schelkin spiral was used an accelera...

Engine Testing Engine Test System

Engine testing involves measurement of rotating speed and torque of the engine by applying load controlled by a dynamometer connected to its output shaft. HORIBA has developed various types of dynamometer for the purpose of engine testing. They are mainly classifi ed into two types; one is absorbing only dynamometer such as hydraulic dynamometers and eddy-current dynamometers, the other is abso...
