DATA ITEM DESCRIPTION
Title: AIRCRAFT MECHANICAL INTERFACE CONTROL DRAWING (MICD)
Number: DI-NUOR-81407C Approval Date: 20150720
AMSC Number: F9569 Limitation: N/A
DTIC Applicable: N/A GIDEP Applicable: No
Preparing Activity: 27 Project Number: NUOR-2015-004
Applicable Forms: N/A
Use/Relationship: The MICD is a signature controlled mechanical definition
physical interface between the nuclear weapon(s), the suspension and release system, adjacent
stores/ordnance, and the aircraft during static and dynamic conditions (take-off, flight and
landing)
. The MICD shall dimensionally define the physical interfaces between nuclear
weapon(s) and the aircraft. The MICD includes information and data, 3D computer models, or
3D models derived from measurement (e.g. laser scan).
a. This Data Item Description (DID) contains the format and content preparation instructions for
the tasks described by MIL-STD-1822, Nuclear Compatibility Certification of Nuclear Weapon
Systems, Subsystems and Support Equipment.
b. This DID is related to DI-NUOR-81409, Certification Requirements Plan (CRP).
(Copies of these documents are available online at https://quicksearch.dla.mil
.)
c. This DID supersedes DI-NUOR-81407B.
Requirements:
1. Reference documents. The applicable issue of the documents cited herein, including their
approval dates and dates of any applicable amendments, notices and revisions, shall be as
specified in the solicitation or contract.
2. Format. Contractor format is acceptable. 3-D STEP file format for 3D models is acceptable.
3. Content. The MICD drawing definition is required to list aircraft version, configuration and
equipment, contain notes/references, a signature block for responsible agency representatives,
and three views of the aircraft. Also included in the definition are the high level model(s) or
views of the external pylon configuration with nuclear stores installed and/or the weapons bay
launchers with nuclear stores installed. The notes are to include the parachute and spin rocket
deployment time, fin unlock time selected for this application, the cartridge, orifice, pneumatic,
gravity deployment callouts, and the required pullout cable for each nuclear store as applicable.
The MICD shall provide engineering data and descriptions that define:
a. The general aircraft monitor and control system information or dimensions and weapon(s)
location(s).
b. The aircraft flight limitation data (or reference) for the worst case configuration including
aircraft angle of attack and sideslip, aircraft load factor, peak angle rates, and peak angular
accelerations for the minimum conditions given in MIL-STD-8591, Airborne Stores, Suspension
Equipment and Aircraft-Store interface (Carriage Phase), Table B-II.
