[FIXED INTERNALLY] WfrGr21 are not affecting FW 190 A-8 aerodynamics

[xvii-Dietrich]

The Werfer-Granate 21 (WfrGr21 / BR21) have no effect on the aerodynamics of the FW 190 A-8 "Anton". This applies to both the loaded and spent rockets.

 

 

Conditions

 

To test, I used the following conditions (mission file attached).

 

21-Jun-1944 12:00, 20 deg C, no cloud.

Aircraft starts air-spawned, with 50% fuel, full guns, WfrGr21 on wings, remove centre pylon.

Normandy map, same location for each over water ( XV68 ), facing east, at 1000m alt.

Gentle dive to sea level (10-20m), then hold until speed reduces to stable values

 

 

Results

 

Once in sustained, level flight, I use the status bar to read off the speed (screenshot attached).

 

 

• On the deck, I can sustain in level-flight 550 km/h with the loaded rockets.
  
• If I fire the rockets, the sustained level-flight speed with empty tubes is 550 km/h.
  
• If I drop the rocket pods (i.e. jettison, without firing), it remains 550 km/h.
  
• If I fire the rockets, and then use the jettison switch, the rocket tubes remain (related bug), but the speed remains 550 km/h.
  

 

 

Conclusion

 

The WfrGr21 rockets have no effect on the aerodynamics, and hence speed, of the aircraft. It is irrelevant if they are not-fitted, fitted, fired or jettisoned.

Tested this again with the new version (v2.5.6.47224).

 

Using the same testing conditions indicated in the first post of this thread.

 

 

• No rockets loaded = 551 km/h
  
• Rockets loaded, then jettisoned = 551 km/h
  
• Rockets loaded, one fired, other jettisoned = 530 km/h (and asymmetry noticeable)
  
• Rockets loaded, none fired = 511 km/h
  
• Rockets loaded, both fired = 511 km/h
  

 

When a rocket has been fired, it is no longer possible to jettison the tube (I regard this as a separate, and significant, bug).

 

When a rocket has been fired, there is no change in the dynamics, even though the tube is empty (I would expect some difference, even if small, this is a minor problem in the scheme of things).
