WildBillKelsoe Posted December 12, 2012 Posted December 12, 2012 the first column is fuze setting ........ OK the second column is (a) desired time of flight? (b) time on final? the third column is (a) dive angle where pipper should be? (b) dive angle where my FPM (tadpole) should be? the sixth column is (a) mils for AOD (b) mils for IPP? the seventh column is ........? stick? I don't get it... and about AOD figures.. are they in Nm or Km or meters? Note IPP figures are in mils. I've roughly attempted a re-draft in Open Office format. Could you guys cross-check it? If somebody with clearer table, much appreciated. AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow.
BlueRidgeDx Posted December 12, 2012 Posted December 12, 2012 (edited) According to the header, the planned delivery is for a 38,000lb jet, against a target located at Sea Level, with a 5 second wings-level "track" time, at either 10° or 30° Celsius (I can't tell due to the scan quality). Column 1 is the Fuze Setting. It sounds like you know what this one is, so I won't get into it. Column 2 is the Fuze Time. It is the length of time that it takes the fuze to arm after release. If the Time Of Fall (TOF) is less than the Fuze Time, the weapon will impact before arming, and will dud. Column 3 is Dive Angle. It is the desired flight path angle during track/release. This is where the TVV should be, not the nose or GBL. Column 7 is Total Sight Setting. Total Sight Setting is the required angular depression of the pipper at release, given the aircraft's planned parameters. It is measured in mils from the Zero Sight Line. For reference, the GBL is depressed 34 mils from the ZSL. If you're fast/slow, high/low, steep/shallow, then this planned number is wrong and your bombs will miss. But unless you're delivering in HARS using the Depressible Pipper, this number is largely meaningless. IFFCC constantly updates the pipper's depression based on current aircraft parameters. Hence the "CC" in CCIP. Column 8 is the Stick Length. It's the distance between the impact points of the first and last weapon released in a ripple. To achieve a desired spacing for a given dive angle, airspeed, and release altitude, you would have to consult a table for the appropriate Release Interval, measure in milliseconds (see column 6). Now, all you have to do is put the desired impact spacing into DSMS, and the release interval is automatically calculated/used by IFFCC. AOD is measured in feet, and sometimes in nautical miles too. Yes, IPP is in mils. Was that a question? Edited December 12, 2012 by BlueRidgeDx spelling is hard 2 "They've got us surrounded again - those poor bastards!" - Lt. Col. Creighton Abrams
WildBillKelsoe Posted December 13, 2012 Author Posted December 13, 2012 man, you came out of the blue.. could you cite your sources? thanks again.

BlueRidgeDx Posted December 13, 2012 Posted December 13, 2012 I think if you google the term "initial pipper placement", you can find some open source information about the bombing triangle and related weapon delivery terms.

It looks like you're aviation, so, pardon me. Thanks again. AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower.

BlueRidgeDx Posted December 13, 2012 Posted December 13, 2012 (edited) No pardon required. Perhaps I misunderstood what you were asking? I didn't reference a specific source to provide the answers, I simply wrote them from memory since I've spent a lot of time familiarizing myself with them over the years. The concepts are applicable to all airframes, as are the terms and definitions. The only thing A-10 specific in my answer was about the ZSL/GBL relationship, and I'm pretty sure that information can be found in the DCS A-10C manual somewhere. The type of information you're talking about is normally found in "Dash 34" Non-Nuclear Weapon Delivery Manuals but those are not publically accessible. I wasn't being crass when I suggested googling "Initial Pipper Placement". There are some very informative pubs there from CNATRA for the T-45C that contain the all of the same bombing theory used by the A-10 (and all other airframes).
