DCS World 2.5 Update

 

This week Eagle Dynamics has moved the Open Beta version of DCS World to the Release version.

Highlights include:
• New MiG-29 flight model, adjusted engine performance
• MiG-29 new pylons, and corrected M1.6 engine stall
• Corrected FAB-250 pylon position
• F-4E and C-130 Iranian skin
• Several AJS-37 Viggen improvements, such as gear and wheel brake adjustments
• DCS: MiG-21bis and DCS: C-101 improvements

For a complete list of changes click here for the DCS website.

For next week’s Open Beta update, the plan is to add new Hornet features and fixes like the Joint Helmet Mounted Cueing System (JHMCS), FPAS page, laser Maverick, and corrected air-to-air radar B-sweep.

DCS World War II Assets Pack Update
The WWII assets pack continues to grow, and the next ground unit will be the M10 “Wolverine” tank destroyer. Based on a modified M4A2 Sherman tank chassis, it includes an open-turret with a 76.2 mm cannon. Produced by the US starting in September 1942, the M10 was the most important US tank destroyer of the war.

Air-to-Air Missile Development Update
A key aspect of modern air warfare is correct modelling of air-to-air missiles. New resources have devoted to further improving this. There are four fundamental aspects that are currently being working on:
• New missile flight dynamics
• Improved autopilot roll, pitch, yaw damper and stabilization
• New autopilot guidance and trajectory calculations
• Modified seeker logic

The AIM-7 is being used as a “test bed” before moving these improvements to other air-to-air missiles once the technology is mature. The AIM-7M is being tested with:
• New missile flight model using updated and more detailed aerodynamic data
• Autopilot navigation system model
• Missile guidance section and seeker

The following video demonstrates the AIM 7 autopilot in a vertical test.

Missile Flight Dynamics
A new feature of the missile autopilot and flight model: stability and control implementation is currently being tested. High altitudes and low air speeds provide low aerodynamic damping moments, and you can see missile motion in detail. Note the control surface deflections. The missile’s autopilot dampens oscillations more quickly than with autopilot turned off. This is just a test thought of the autopilot and aerodynamics of the missile. Naturally, air-to-air missiles are not designed for such low air speeds. In fact, the minimal IAS at intercept for an AIM-7 is about 700 km/h. At this speed, it’s capable to reaching 5g’s in less than a second.

Tasks in this area are still working on includes the supporting math for thrust vectoring and refactoring/optimization.

Missile Autopilot
Control systems and autopilot on missiles is currently being worked on. This includes:
• Mathematical model of torque balance system (AIM-9-like missiles)
• Inertial navigation system + data link for modern missiles
• Сorresponding aircraft weapon systems

Almost every new missile needs its own autopilot type (based on common model)

Missile Seeker
For the guidance systems and seekers, there is a lot of work for the future. Building from the common mathematical model, DCS will create detailed models for many seeker types. “When this effort is complete, we believe we’ll have the most detailed air-to-air missile simulation in an entertainment product.”

A Worthy Cause
Former Hornet pilot and author C.W. Lemoine will be flying the DCS World Hornet and comparing it to his own experience if more than $7,500 of donations can be raised for victims of hurricane Michael.
