Introduction

The function of a propeller on an aircraft is to present propulsive push. This lab report was aimed at studying and analysing the propeller and some engine properties of a Cessna 310R. The axial momentum theory, advance rate and the strength method for fuel flow evaluation are used from this analysis.

Definition of propeller parameters

ACTIVITY 2

Ahead speed: The rate of movement/ advancement in the propeller in accordance with the air. Rpm: This is the rotating speed in the propeller, it is measured in revolutions per min. Mtip: Mach Quantity tip, this can be the quality from the propeller tip to reach the mach quantity as a result of embrace RPM. No . of blade: A propeller has a volume of blades, within a Cessna 310, the number of cutting blades is 3. Diameter (d): the distance over the circle sweptВ by the extreme guidelines of the propeller blades. Inside the majority of situations, the larger the diameter the greater the propeller efficiency. Pitch ((): The pitch is known as a measure of the orientation in the propeller on the plane typical to the axis of rotation. reference series for the calculation from the pitch is a chord. Type of blade section: cross portion of a propeller blade within a plane seite an seite to that made up of the axis of rotation. Chord syndication along radius: This is the different distribution in the length of the blend from the industry leading to the trailing edge because of geometrical form of the blasГ© section. Chord length in the hub is greater than on the tip. Idea geometry: This is actually the extreme element of a propeller at the tip which is geometrically thinner than the rest of the propeller blade. Link geometry: This is actually the root of the propeller which can be quiet bigger than the remaining portion of the propeller blade.

Propeller stream tube: This is the axial way and change in flow energy along a stream-tube starting upstream, passing through the propeller, and throughout the downstream. [pic]

Propeller disk: This is total area on which the propeller rotates.. Propeller is considered as being a rotating drive instead of consisting the blades which are spinning in the air. The rotating hard drive imparts axial momentum to the air getting through it.

ACTIVITY 3

Measuring engine rpm vs gas flow via cockpit arrangement. The desk below displays the assessed values in the fuel movement at 1000 rpm, truck rpm and 2000 rpm.

|RPM |FUEL MOVEMENT (kg/s) | |1100 |0. 003527916kg/s | |1500 |0. 004787886kg/s | |2000 |0. 007811814kg/s

ACTIVITY 5

Axial Momentum Theory

This is certainly a assumptive mechanism in which the rotating power of a propeller is changed into useful thrust. In this theory, the propeller is considered as being a rotating hard disk drive instead of consisting the cutting blades which are rotating in the air....
