Baluncore's latest activity
-
Baluncore replied to the thread Engineering AM-AM and AM-PM graph generation in LTSpice.I assumed it was when your bias control circuit began to regulate, or the output voltage saturated. Maybe change the step parameters to... -
Baluncore replied to the thread Graduate Project Progress Report and possible Radio Astronomy Technique?.There is a tradeoff, is it easier to synchronise the internal 1'st LO synthesisers of two SDRs, or to build two RF front-ends with 1'st... -
Baluncore replied to the thread Engineering AM-AM and AM-PM graph generation in LTSpice.Modified the signal input, so only one parameter is needed. I have given you a .STEP command. For vin = 1.0v to 3.5v step 0.5v... -
Baluncore replied to the thread Engineering AM-AM and AM-PM graph generation in LTSpice.It is difficult to do those simulated tests because you have two trapezoidal inputs, with feedback from the amplifier output to the... -
Baluncore replied to the thread High School How do walk-in freezers not give people hypothermia? [they do].Old ice is not amorphous, it is a crystalline solid, like a rock made from crystals of H2O. Glaciers flow, and skates glide, because... -
Baluncore replied to the thread Aero/Hydro-dynamic Streamlining as a function of medium.Commercial jets have a cylindrical shape fuselage, between a parabolic nose and a conical or wedge shaped tail. The cylinder maximises... -
Baluncore replied to the thread Undergrad Ramjet effect on drone.All stagnant space connected to the inlet would be subjected to that internal pressure. A pinhole, on the front of a hypersonic... -
Baluncore replied to the thread Undergrad Ramjet effect on drone.The pressure will fall from the inlet to the outlet as the radiator will partly obstruct the airflow, while the heated air will increase... -
Baluncore replied to the thread Aero/Hydro-dynamic Streamlining as a function of medium.I disagree. Aircraft have a sharp edge convergence at the rear to reduce wake and drag. They also have a blunt or spherical nose, where... -
Baluncore replied to the thread High School Using energy principles to find equilibrium depth of floating object.As the body displaces fluid, the fluid surface will rise, so the reference from which d is measured is changing. -
Baluncore replied to the thread Undergrad Ramjet effect on drone.I would expect the efficiency of both cooling and thrust development to be proportional to the temperature difference between the inlet... -
Baluncore replied to the thread High School How do walk-in freezers not give people hypothermia? [they do].Because warmer ice flows, and bubbles of historical air in the ice can move. -
Baluncore replied to the thread Undergrad Ramjet effect on drone.At 500 kph, the ram air pressure will be about 1.7 psi. The rocket envelope will need to handle that internal pressure, along the sides... -
Baluncore replied to the thread High School How do walk-in freezers not give people hypothermia? [they do].Because they store ancient ice cores, not food. -
Baluncore replied to the thread Collection of Science Jokes P2.At low temperatures, Ad forms naturally into tangles of flat, flexible crystals, that have a distinctive red colour.
