    Determining the acceleration of an aircraft

    Using an example taken from Wikipedia (https://en.wikipedia.org/wiki/Williams_FJ44#Specification), I took the values from FJ-44-1A and did some calculation. Formula (https://www.grc.nasa.gov/www/k-12/airplane/sfc.html): TSFC = Fuel Consumption in lb per hour/Thrust in lbf 0.456= Fuel...

    Determining the acceleration of an aircraft

    Hi guys, I would like to ask a question with regards to TSFC (Thrust Specific Fuel Consumption). The formula for calculating TSFC is fuel flow (kg/hour) divided by the thrust being generated by the engine at that point of time. Is it correct to assume that the fuel flow changes as you increase...

    Determining the acceleration of an aircraft

    Ok. I will try to convince them that the engine thrust calculation is not feasible and I should just use the thrust value given by the manufacturer for better accuracy.

    Determining the acceleration of an aircraft

    You are correct. I'm trying to figure out an engine that can give me a maximum thrust value of 14,000 N. The formula from NASA's website is too difficult for me to figure it out myself. The thrust value is taken from Pratt and Whitney PW615F which is capable of generating a maximum take-off...

    Determining the acceleration of an aircraft

    Thanks you guys for providing me the assistance. Right now, I need to calculate the thrust that can a turbofan engine can produce using F=ma equation. However, I'm not sure how I can approach it. Can I use a hypothetical thrust value and work out the calculation backward? For example, if my...

    Determining the acceleration of an aircraft

    Thank you for the reply. Let's say my aircraft can produce a maximum take-off thrust of 14000 N, how can I work out the calculation? Can I use the F=ma formula to work out the acceleration? Do pilots always go for maximum engine thrust during take-off?

    Determining the acceleration of an aircraft

    Hello everyone. I'm currently doing a research on aircraft performance for my school project, which require me to design an airfoil to suit a specific mission. I'm not very familiar with the formulas used for calculating the aircraft performance and I would like to seek help from the forum...
