Explore the McDonnell XF-85 Goblin through a curated digital collection of historical pilot documentation, NACA research memorandums, McDonnell development records, Westinghouse engine documentation and technical illustrations. Original source material is presented separately from modern Sicuro Publishing research and informational reports.

This is a living aviation archive. Further material is planned over the coming months as the collection develops. The manifest describes the present scope, not a fixed final inventory.

Historical and research context

The Goblin represents an unusual approach to bomber escort: a compact jet fighter designed for carriage within a larger aircraft and recovery using a hook-and-trapeze arrangement. The collection brings together sources for studying the aircraft’s configuration, aerodynamic investigation and development, rather than relying on a single retrospective account.

Original aircraft and engine documentation

• Preliminary Pilot’s Handbook for Army Model XP-85 Airplane, McDonnell Report No. 765. The historical XP-85 designation is retained as printed on the cover.
• Characteristics Summary: Fighter XF-85, dated 7 June 1949. Aircraft configuration, powerplant, features and experimental status.
• Handbook of Overhaul Instructions: Models J34-WE-22, -30, -34 Aircraft Engines, AN 02B-110BA-3. The supplied cover states that it supersedes the publication dated 15 July 1949, revised 1 April 1950. This is a multi-model engine reference, not an XF-85-specific airframe manual.

NACA research records

The supplied research series comprises the following individually identified memorandums. Report identifiers are preserved for archival searching; historical XP-85 and later XF-85 terminology may differ between documents.

• NACA RM L7C10, dated 6 March 1947: free-spinning and tumbling investigation of the XP-85 model.
• NACA RM L7C26, supplied file dated 19 March 1947.
• NACA RM SL7C27, supplied file dated 19 March 1947.
• NACA RM SL7I11, dated 13 October 1947: supplementary free-spinning tests with a conventional tail arrangement.
• NACA RM SL7J16, supplied file dated 17 November 1947.
• NACA RM SA8J22, dated 22 October 1948: investigation of the McDonnell XP-85 airplane in the Ames 40-by-80-foot wind tunnel, pressure-distribution tests.

McDonnell factory report records

• Report No. 1086, supplied file dated 28 February 1949.
• Report No. 1179, supplied file dated 23 May 1949.
• Report No. 1226, supplied file dated 1 September 1949.

Technical drawings and illustrations

The supplied illustration set includes a major-parts exploded drawing, an XP-85 three-view sheet and an annotated inboard cutaway associated with Report No. 1226. These are historical engineering references, not simplified construction plans, manufacturing authorization or an exhaustive aircraft drawing set. They assume technical literacy; coverage, dimensions and legibility vary with the surviving source.

Sicuro Publishing research and informational supplements

Modern editorial companions are kept distinct from the original McDonnell, NACA and engine publications. They provide research context and document navigation, not official manufacturer instructions or independently validated operating data. The supplied report files are:

• McDonnell XF-85 Goblin Technical Report: aerodynamic reports, engine notes and handling studies.
• McDonnell XF-85 Goblin Technical Report, expanded compilation with flight-log and NACA-reference sections.
• XF-85 Goblin Unified Master Technical Profile & Research Report.
• XF-85 Goblin Unified Master Technical Profile & Operational Architecture Report.
• XF-85 Goblin Unified Master Technical Profile, expanded structural and aerodynamic discussion.
• XF-85 Goblin Core Engineering Data & Wind Tunnel Summary Report.
• McDonnell XF-85 Goblin Reference Directory / research index and bibliography.

Bibliographical references identify further research leads; citation in an index does not mean that every referenced publication is included in the downloadable collection. Overlapping modern reports are companion versions, not additional original factory manuals.

Photographs and video

Photographic reference material complements the technical archive. A dedicated OAL presentation video is being created by Silvio and is planned for a future listing update; it is not represented as available now.

Format and digital delivery

Digital archival documents in PDF format, with supporting image files. No physical books or aircraft parts are supplied. Instant digital access is provided through the purchase download service once the collection is released and its files are connected. Files supplied in compressed RAR/ZIP archives must first be extracted using an archive utility such as 7-Zip or WinRAR on Windows, or The Unarchiver on Mac; extracted PDFs open in a standard PDF reader. Scan quality, printability and text searchability depend on the original document.

Historical-reference boundary

Engine overhaul and other maintenance-related material is preserved for historical research, education, simulation and non-airworthy museum reference. It is not current revision-controlled maintenance data and must not be used to authorize inspection, overhaul, repair, manufacture or flight operations.
