Monocoupe 90

The Monocoupe 90 was a two-seat, light cabin airplane built by Donald A. Luscombe for Central States Aare Inc.. The first Monocoupe (Model 5) was built in an abandoned church in Davenport, Iowa, and first flew on April 1, 1927. Various models were in production until the late 1940s.

Development

The Monocoupes were side-by-side two-seat lightplanes of mixed wood and steel-tube basic construction with fabric covering. A braced high-wing monoplane with fixed tailskid landing gear, and the reverse curve rear fuselage lines that were to become one of the signature identifier features of the Monocoupes. The fuselage framework was built up of welded steel tubing in a rigid, triangular-framed Warren truss form for the side panel structures, heavily faired to shape with dural metal sheet formers and wooden fairing strips. The wings were built up of solid spruce spars with wing ribs of basswood webs and spruce cap-strips. The leading edges were covered with dural metal sheet and the entire framework was covered in fabric.

The aircraft was powered originally by either a 60 hp (45 kW) Anzani engine or the unsuccessful 65 hp (48 kW) Detroit Air Cat radial. The Model 22 was the first light aircraft awarded a type certificate (number 22) and in 1930 it was fitted with the Velie M-5 62 hp (46 kW) five-cylinder radial engine to become the Model 70.

In 1930 Monocoupe introduced the Model 90 with refined lines and a fuselage that was slightly longer and wider, this being sold in Model 90 and Model 90A versions with a 90 hp (67 kW) Lambert R-266 radial engine. The Monocoupe 90 DeLuxe introduced trailing edge flaps, wheel speed fairings and an improved engine cowling. The Model 90AF was fitted with a 115 hp (86 kW) Franklin engine. The Model 90AL had Avco Lycoming engines. The Model 90J was introduced in 1930 with a 90 hp (67 kW) Warner Scarab Jr engine.

The final two high performance Monocoupe models developed from the Model 90 were the Model 110 with a 110 hp (82 kW) Warner Scarab, and the Model 125 with a 125-hp (93 kW) Kinner B-5 engine. The Monocoupe 110 Special was a clipped wing racing aircraft. The Monocoupe Model 70V of 1932, had the low-powered 65-hp (48-kW) Velie M-5 engine reintroduced to provide more economical operation at the cost of a fall in performance.

In 1941 Monocoupe combined with three other companies to form Universal Molded Products Corp. 20 Model 90AFs were bought by the USAAF, who designated them the Universal L-7, for transfer to the Free French Forces. One was lost during delivery. Aircraft production halted during World War II, resuming briefly in 1948-1950 under the name Monocoupe Airplane and Engine Corp.

The last of this remarkable line of two-seat aircraft was the Monocoupe D-145 of 1934, a high-performance version with a slightly enlarged cabin and powered by a 145 hp (108 kW) Warner Super Scarab engine.

    .

    19 delivered early 1943 by sea to Abu Sweir, Egypt, to be reassembled by RAF MU 109. Main delivery to create a flying school (GE 11) in Rayack, Syria, opening September 1, 1943. The Monocoupe 90 was too sensitive to be used for basic training and many accidents occurred until school disbandment January 4, 1944. One aircraft survived the war and remained on the French civil register until written-off in 1962. 5 aircraft delivered to Madagascar in early September 1943 and operated by Escadrille d'Avions Sanitaires et de Liaison (EASL = Liaison and Medical Flight) based at Ivato. EASL became Escadrille de Liaison et de Commandement (ELC) on January 1, 1944, then SAL-51 and last SLA-50. The last two Monocoupes were sold to local aéro-club in 1948.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
