Well actually a few.

1) Has anyone gotten the bomb cradle"wishbone" to lower before a bomb run?

2) Where do the .50 cal brass get ejected from?

3) Anyone noticed that the floor porthole is no longer transparent?

4) and finally: any way to get all of those sights/reticles to drop down or is that not at all possible? I assume they were fer machine guns and a diff one fer the bombs? Or am I wrong?

Thanks,
Mjollnir

The SBD had 4 ports, 2 on each side, on the underside of the plane to the rear of the cowling. There was a small square port just ahead of the wing-root for ejecting the links. There was a rectagular port just behing that on the wing root that ejected the shells.

The cradle does not lower by itself. It is attached (sort of) to the bomb, and when the bomb is released, the cradle swings down keeping the bomb from going through the arc of the prop. I believe that it was springloaded, and once the bomb was away, it would come back up to it's retracted position. The weight of the bomb is what makes it swing down.

@ Skychimp & Razor: Thanks guys!!!

@ RAzor: So if the weight of the bomb causes it to swing down what happens when the plane is on deck with a bomb?All I can picture is the bomb dragging along as the plane moves. Was there an activation control to lower it once in flight? I understand how you describe it but now it leaves me to wonder: is the cradle "lock pinned" until the plane gets airborn at which time the pilot un locks it? I always thought that the cradle lowered automatically when a dive angle was exceeded so it wouldn't release into the prop itself and also give a better vertical drop. Level bombing doesn't much hold this wonder fer me just dive bombing.

my guess is that the bomb was not just attatched to the cradle but also to a bombrack of some sort that carries the full weight of the bomb untill it releases the bomb then the cradle starts to work in the way Razor just described.

Well then at some point there almost has to be some interaction between the pilot and plane.
Examining the pic that SkyChimp posted I cant see anywhere that there would be a hardpoint to hold it fast.When I look at the "wishbone" I see what looks like a lever just behind the vertical shaft that goes thru the fuselage. I can see the mounting points fer the bomb on the wishbone and what seem to be rubber dampers fer whatever reason, but I cant see any other place that would look even remotely strong enough to hold up a bomb as far as in conjuction with the cradle.I wish I had the talent to alter Skychimps pic so I could point out what I am referring to. But if you go straight above the 2 o's in too and you'll see what I think is a pilot activated lever to deploy the "wishbone". But then I think of the strength required to manually activate such a thing.Maybe hydraulic??
Anyone have any good links to either a pilots manual or any first hand accounts from pilots who describe what happens??
Oh yeah: Looking just aft of the cradle when retracted there seems to be an access panel. Definately not where I would put a hard point. http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif

Now I dont see Any other points of mounting in conjunction with the cradle. I see what appear to be yet more rubber dampers but nothing as far as additional hard points. http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif

This plane has been modified, originally there was a shallow well that the top part of the bomb nestled into. there was a hardpoint there for the bomb to attach to. If you look closely on the picture above you can see the seam aft of the bomb cradle where the fairing has been added. I'll try to find a picture of an unmodified Dauntless

The bomb cradle could hold the weight of a 500lb bomb by itself.

For a 1000lb bomb, a panel was removed and a fairing was installed to access the centerline attachment points and creat enough clearence .

Looks like in the picture the bomb centerline attachment points are faired over.

Well, I can't find a Picture on the web which illustrates the bamb cradle, but if you can find the Squadron/Signal SBD in action book, there are several pictures which illustrate the bomb cradle, the bomb, and how the bomb was loaded.

@Chimp:

Yeah no kiddin!! Thanks man!! Great!!

Now as I have read on the page of that book when are we gonna get "Smoke Tanks" so we can lay down a smoke screen? Guess thats goin a lil too far, huh?

SkyChimp: Does it say HOW the cradle was activated/deployed? Manual,dive angle activated,Hydraulic??

If I may ask another question about the SBD. When in cockpit and looking down to the right and left, there are honking big cables anchored in those spots which then trail aft to the area behind the pilots seat. I assume that they may have some connection to the arresting hook (safety device?) as they appear to have some slack.

Do any of the pilots here have knowledge of these?

The SBD is becoming one of my favorites (I have wrecked more than a few in some odd carrier landings "controlled crashes").

Cheers and happy holidays.

The cradle wasn't "activated" per se, the bomb was attached to the fuselage hard point with bomb shackles, and to the swing arm with pins on the side of the bomb. The pins on the bomb fit into sockets on the swing arm. When the bomb was released, the weight of the bomb would cause the arm to swing down. When the arm was fully extended, the bomb would slip out of the sockets on the swing arm. The only purpose of the swing arm was to ensure that the bomb was clear of the propeller arc before it began falling forward, it did not supprt the weight of the bomb.

Having been curious about this mechanism as well guys....

I have this same ref. material and on the next/facing page adjacent to the one SkyChimp graciously posted (p.43) there are some good pics of the wing station bomb racks. Those pictures look like side views of the same type of rack mechanism that is shown on centerline from below the belly in SkyChimps posted pic.
Also on the page posted you can see that the aft ends of the bomb displacement yoke are "U" shaped and completely open to the rear - this "Attach point" could never have been used as the primary mounting point for the ordnance. It serves only as the others have pointed out.
"SkyChimp: Does it say HOW the cradle was activated/deployed? Manual,dive angle activated,Hydraulic??"
On p.37 of the ref. book it identifies the controls on the left side of the cockpit. The control quadrant below the throttle quadrant is for the ordnance, the forward red lever being bomb release, and the shorter/aft lower red lever is the bomb arming lever. This quadrant is fed by only small dia. (Guessing 3/32") cables so that answer would be cable arming and release. These levers are visible in both SBD's while flying the sim.
"If I may ask another question about the SBD. When in cockpit and looking down to the right and left, there are honking big cables anchored in those spots which then trail aft to the area behind the pilots seat. I assume that they may have some connection to the arresting hook (safety device?) as they appear to have some slack."

The large dia. cable mounted on each side of the cockpit is for hoisting and storing the aircraft since it did not have folding wings it was "Stored" by being suspended from the hanger deck ceiling. The cable remained in the plane at all times.

The airbrake mechanism on this bird is what really stands out to me as unique.
However, the mounting of 500lb bombs at the wing stations in the sim continues to facinate me as well http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

What a great plane, Happy Holidays to you guys.

Thanks for solving my cable mystery BigA. Those points must also be center of gravity with fuel full (all aircraft on hanger bay are fully fueled to reduce danger of explosion... according to what the Navy told me on the Hornet).

I have been reading about the Douglas(?)SB2U Vindicator and the Curtis SB2C/A-25 Helldiver. I can't determine, so far, whether the Dauntless or the Helldiver was the most effective.... much more reading to do.

Cheers and happy holidays and thanks again.
