3D Model and Sounds

The TorqueSim SR20 has been meticulously detailed to provide for the most in-depth visual model for the SR20 possible. The aircraft makes full use of 4K PBR textures, ensuring the highest level of visual fidelity. All the different materials are accurately represented from samples from the actual aircraft!

The FMOD sound pack has been the result of hundreds of hours of source audio, carefully recorded from the real aircraft. Recordings of the engine on the ground, and in-flight have provided for a highly-accurate and immersive sound pack replicating the real aircraft. Every switch, knob, lever, and button have been modeled in the sound-pack.

Engine Model

The SR20 is equipped with a normally aspirated Continental IO-360-ES capable of 200 HP. The TorqueSim custom physics model is the most accurate simulation of a piston engine for X-Plane! The simulation models the mass flows of air and fuel through every part of the engine in real time. Air enters the engine through the air filter, flows through ducts, passes obstacles like the throttle plate, burns the fuel and leaves the engine as exhaust gas. Pressures and temperatures are calculated in every section independently, all contributing to the different segments of the simulation. All engine parameters are tuned against a huge database of real engine log data to ensure maximum possible accuracy in all phases of flight. The entire engine simulation runs on a separate thread from the main simulator. This allows for the timing necessary for proper simulation, independent of sim frame-rate, but also ensures that the model has a near-zero performance impact on the simulator!

  • Mass flows of air and fuel, pressures and temperatures calculated in every section of the engine independently
  • Torque generation algorithm based on air-fuel ratio closely reflects engine performance graphs and enables highly accurate leaning behavior
  • All engine parameters are tuned against a huge database of real engine log data to ensure maximum possible accuracy in all phases of flight
  • Normal, cold, hot, flooded and false starts simulated employing the custom fuel system
  • Engine temperatures calculated per cylinder depending on numerous internal and environmental factors, all components take their real times to cool down
  • Custom G1000 %Power algorithm based on sensed engine parameters and not actual engine power output
  • Custom oil system with oil cooler, filter, degradation and consumption
  • Custom prop governor with propeller control linked to throttle
  • Real engine set screw for maximum fuel flow can be turned
  • Cylinder detonation (engine knock), low engine temperatures increase friction and wear, spark plug fouling, improper magneto grounding and numerous other custom failures

G1000 Perspective

Significant work has gone to enhancing the Laminar G1000 to provide many of the functionalities in the G1000 Perspective suite. Synthetic Vision, as implemented in HotStart’s TBM900 and TorqueSim’s Pocket Rocket has been integrated. The engine pages and sidebar have been modeled fully to provide the necessary details for proper engine management. Lean-assist functionality has been integrating assisting in the proper leaning of the engine. Checklists have also been integrated onto the G1000 providing easy access to the necessary preflight, starting, in-flight, post-flight, and emergency procedures. In addition to these additions, numerous other tweaks were implemented including matching the Perspective’s Top-Bar details including % Power, and destination calculations, in addition to the integration of “Know your Limits” and the fuel calculator system (which we implemented as a custom interface for refueling the aircraft!).

All these customizations are designed to also work perfectly with the RealSimGear G1000 and Perspective Package. Learn More about the RealSimGear Hardware

Electrical System

The SR20 electrical system has also been intricately detailed, ensuring every last breaker and switch is modeled. The dual-batteries are simulated with a custom lead-acid battery simulation. The dual-alternator setup and Master Control Unit have been intricately tuned to interface with the rest of the simulation. All electrical busses and circuit breakers are individually simulated to provide for the most in-depth of simulation. All the intricacies of the SR20 electrical system including alternator drop at low RPM are modeled.

Fuel System

The SR20 fuel system has all been custom simulated, providing for unparalleled accuracy in-flight. It models all the details down to the fuel lines and injector nozzles! Fuel temperature is calculated and vapor is formed in the lines under the right environmental circumstances. This also allows for the recreation of all engine starting characteristics usually found on an aviation piston engine like normal, cold, hot, flooded and false starts. So be sure to understand the importance of your boost pump both on ground and in flight! The complex behavior of the engine driven and electric fuel pumps as well as the fuel manifold and metering unit are simulated. Changing bank and attitude of the aircraft affect sloshing in the tank, thus causing the indicated fuel quantity to differ.

  • Main and Collector Tanks
    • Collector tanks prevent fuel starvation during uncoordinated maneuvers
    • Fuel sloshes depending on sideslip angle, affecting float-sensed quantity and strainer coverage
  • Every component in the fuel delivery path simulated and contributing to overall system behavior
    • Boost and engine-driven fuel pumps and pressures
    • Fuel metering unit and spring-loaded fuel manifold
  • Vapor Lock
    • Fuel vaporizes after shutdown depending on engine temperatures and requires special startup procedures
    • Hot fuel can cause vapor formation and power fluctuations at high altitude in flight, suppressed by use of the boost pump

Maintenance and Failure Model

The SR20 also features an engaging and beneficial maintenance, wear, and failure model. This aspect of the simulation makes sure that the plane is flown safely and without damage. Excessive wear will be affecting airframe performance and safety, addressed through a realistic concept of runtime-based and annual inspections. The entire wear and failures logic is built on top of the physics model for engine, airframe, and fuel systems. This also includes truly unique features like cylinder detonation driven by the physics engine. Tires flatten, brakes fade when hot, the propeller experiences FOD on unprepared surfaces and much more to discover. Probability distributions tuned with real-world data are used to reflect the increasing likelihood of failures with component runtime.

High-Fidelity Flight Model

The flight model is designed with unparalleled accuracy. The tuning of the aerodynamic profile required hundreds of hours of careful tuning to accurately match the real-world characteristics. The base model was created by X-Aerodynamics, and further built upon to match the aerodynamic quirks of the real aircraft to the limit of the simulator!

  • Custom airfoils and highly accurate fuselage shape
  • Stall strips and cuffed wing design with unique stalling characteristics
  • Accurate control surface areas and deflections for realistic turn rates

Tail Number Livery Customizer

The tail number can be dynamically changed on the aircraft! There are many configuration options to make the plane yours - from changing the tail number color, placement, outlines, drop shadows, all the way to painting it on the wings!

Persistent and Performance Tuned

The countless systems are all designed with persistence in mind - when you shut down the aircraft, you will return to it in the state in which it was left, the engine components will take their real times to cool. This encourages the proper care and handling of the aircraft, and shows the consequences of reckless flying. These systems are also designed to run on computers of many different specs. All the systems are programmed in C/C++ using the X-Plane SDK. No compromises were made for simplicity. The plugins make significant use of multithreading to have the absolute minimum processes running on the main simulator thread, thus helping keep X-Plane performance at its maximum!
