Hi,does anyone know how many sensors a typical rocket have and what they are? Where can I find such a list?Senmeis
Depends on the rocket. What kind?senmeis said:Hi,does anyone know how many sensors a typical rocket have and what they are? Where can I find such a list?Senmeis
Just conventional fluid rocket, not so specific as Delta.Senmeisruss_watters said:Depends on the rocket. What kind?
you are still being very vague ... get specific !senmeis said:Just conventional fluid rocket, not so specific as Delta.Senmeis
"In 1969, the Saturn 5 1st stage had over 900 sensors poling at up to 120 samples per second and had about a dozen live feed video cameras..."senmeis said:Just conventional fluid rocket, not so specific as Delta.
Likely correct, but please remember Saturn 5 had 5 engines in first stage. Modern stages (with exception of Falcon) usually have 1-2 engines.Tom.G said:"In 1969, the Saturn 5 1st stage had over 900 sensors poling at up to 120 samples per second and had about a dozen live feed video cameras..."
"I would think it is safe to say that the sensor load of data at SpaceX was likely higher than what was seen in 1969..."

Well, one spec for 30-ton 2-engine fighter jet i seen back in 2004 called for 256 sensor inputs in electronics bay. Will be actually lower count because some inputs are unused. Older fighters with network based on milstd-1553 were limited to 32 sensors per bus. Plus some sensors wired as stand alone.russ_watters said:I can believe the numbers for the Saturn V, but the numbers for modern rockets seem shockingly/impossibly low. My cell phone and a single industrial motor controller each have around a dozen sensors. I'd be shocked if a SpaceX rocket didn't have thousands or tens of thousands.
The number of sensors used in a rocket can vary depending on the specific design and purpose of the rocket. However, on average, there are usually between 500-1000 sensors used in a rocket.
There are various types of sensors used in a rocket, including temperature sensors, pressure sensors, accelerometers, gyros, and many others. These sensors are used to monitor and collect data on different aspects of the rocket's performance and environment.
Sensors in a rocket work by measuring physical quantities such as temperature, pressure, and acceleration. They then convert these measurements into electrical signals that can be transmitted to the rocket's control systems for analysis and adjustment.
Sensors in a rocket undergo rigorous testing and calibration before being used in a launch. This includes subjecting them to extreme conditions, such as high temperatures and vibrations, to ensure they can withstand the harsh environment of space.
If a sensor in a rocket fails, it can potentially impact the performance and safety of the rocket. Therefore, redundant sensors are often used in critical systems to ensure that if one sensor fails, there is a backup to continue collecting data and making adjustments as needed.
