## Frequently asked questions about AeroEngineS

### What types of aircraft engines can AeroEngineS simulate?

AeroEngineS can simulate subsonic and supersonic 1-spool turbojets, and various configurations of 2-spool and 3-spool turbofans. It also includes simulations for hybrid precooled rocket engines and ramjet engines.

### Does AeroEngineS calculate aircraft emissions?

Yes, AeroEngineS calculates emissions for aircraft engines during both the LTO (Landing and Takeoff) cycle and cruise. It supports emissions calculations for subsonic 2-spool and 3-spool turbofan engines.

### How does AeroEngineS predict compressor map operating points?

The app uses scaling techniques on existing HPC (High-Pressure Compressor) maps and artificial neural networks to interpolate data from existing maps for operating point prediction.

### What working fluids can be used in the rocket engine simulation?

The Hybrid Precooled Rocket Engine simulation in AeroEngineS can analyze thermodynamic cycles using Air, Hydrogen, and Helium as working fluids.

### Does AeroEngineS automatically calculate ambient conditions?

Yes, AeroEngineS automatically calculates ambient conditions based on the flight altitude using the International Standard Atmosphere model. It also automatically calculates Cp, gama, and R for each component based on temperature and fuel-to-air ratio.

### What is the age rating for AeroEngineS?

AeroEngineS has an age rating of 4+, making it suitable for a wide range of users. It is available on iPhone, iPad, and iPod.
