reported SD10 scatter pattern incorrect for Jabo attack

[xvii-Dietrich]

[[  Had to re-edit this. The forums destroyed the text of the original.    ]]

 

 

The distribution pattern (scatter of the sub-munitions on the ground) is incorrect for the AB250 SD10.

 

Instead of an elongated 200x60m pattern, the bomblets fall in a 45m dia circle.

 

Track file attached.

Quick re-write. The forums destroyed the text of the carefully worded/presented original. (Can we have a raw markup/HTML editor instead?))

[Walshtimothy]

Yes these issues need resolved , hopefully these testing provided by dietrich here will help ed resolve this quickly

The Anton left early access 15 months ago and these have never worked properly. Every few months I'll give the cluster munitions another try and every few months I'll be sorely disappointed when zero progress has been made in actually bringing the bird out of EA status.  Please ED give some priority to getting all these bugs sorted.

Thanks for the detailed write-up @xvii-Dietrich

 

Would be nice if we could get resources dedicated to this issue right away.

Could you please provide the track from single player on the Caucasus map?

What is bombing params: speed, altitude?

[xvii-Dietrich]

A test was carried out on the Caucasus map as follows.

 

Setup

 

Four FW 190 A-8s are included. They are set to bomb an intersection on an airport runway. The runway is approx. 60m wide (which is the expected lateral scatter of the submunitions). White shipping containers have been used to indicate the centre line, expected longitudinal distribution (200m) and lateral distribution (60m).

 

Speeds

 

The aircraft are set to different speeds, 550, 500, 450 and 400 km/h. As they approach the target, they adjust their speeds to 510, 486, 459 and 453, respectively. I presume this is the AI adjusting for the bombing run. A .trk file is provided to allow extraction of exact speeds at relevant stages of the attack.

 

Altitudes

 

The runway height is 30m altitude, and the aircraft are set to 530m altitude. This gives a drop altitude (dt. Abwurfhöhe) of 500m. This matches the historical data that I have (please see the reference and attachment in the original post in this thread). Likewise, see the .trk file for exact altitude data.

 

Result

 

In all cases, the distribution pattern is approx. ca.90m long, by ca.60m wide. The width is correct, and matches the historical data. The length is about half of what it should be. The expected historical pattern is ca.200m long by ca.60m wide.

 

The track and a screenshot of a distribution pattern is attached.

Thank you xvii-Dietrich!

Will check.

Hope this gets resolved asap.
