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


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.


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


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....
