What are the main advantages of hydraulic systems?
- excellent power to weight ratio;
- high power transmission efficiency;
- flexibility in installation;
- resitance to overload conditions;
- high reliability;
- fast response;
- precise position and load control.
What is the formula for Pressure [Pa]? (Hydraulic Actuator)
\(P = {F \over A}\)
F= Kraft
A= Fläche des actuator
What is the formula for Power [W]? (Hydraulic Actuator)
\(P = {W \over t} = {F*d \over t} \)
F= Kraft
d= Distanz
How do you calculate the area of a circle?
\(A = {\pi *r^2}\)
What is the formula for the TSFC?
\(TSFC = {m_f \over F}\)
What is the formula for the specific thrust?
\(spec. thrust = {F \over m_0}\)
Explain the ideal Otto cycle.
The theoretical Otto cycle comprises an isentropic compression (process 1-2), a constant volume heat addition (process 2-3), an isentropic expansion (process 3-4) and a constant volume heat rejection (process 4-1).
What is the formula for the piston velocity?
2*s*n
