Robin DR400

The Robin DR400 is a wooden sport monoplane, conceived by Pierre Robin and Jean Délémontez. The Robin DR400 first flew in 1972 and is still in production. The current model is designated 'DR401'. It has a tricycle undercarriage, and can carry four people. The DR400 aircraft have the 'cranked wing' configuration, in which the dihedral angle of the outer wing is much greater than the inboard, a configuration which they share with Jodel aircraft. This model is considered easy to fly by many and quiet during flight due to its wooden frame.

Development

The Robin DR300 series were developments of the earlier DR.221 Dauphin and DR.250 Capitaine with a tricycle landing gear. The first variant was the DR340 Major, a tricycle landing gear version of the DR250 Capitaine which first flew on 27 February 1968, followed on 21 March 1968 by the DR315 Petit Prince, a tricycle landing gear version of the DR221 Dauphin. The DR315 was later replaced by the DR300. In 1972 an improved version, the DR400 was introduced with a forward-sliding canopy.

Design

The wing is a distinctive feature of the Robin DR400, and is what immediately separates this aircraft visually from other similar light aircraft. It is a derivative of the earlier Jodel designs, is light, stiff and strong, with the dihedral of the outer panels imparting substantial lateral stability in flight. Being fabric covered, it presents a smooth surface to aid airflow, unhindered by the typical overlapping panels or rivets found on metal aircraft.

The secret to the DR400's relatively high performance lies in the pronounced washout in the outer panels. Since they have a lower angle of attack to the airflow than the centre section, they create less drag in cruise flight. This characteristic also imbues rather benign stall behavior and the DR400 consequently does not suffer from the need to install retro-fixes like leading edge stall strips.

    General comments are accessed via the "BLOG En" button.

    Comments are moderated, so please allow some delay before they appear, specially if you are outside Europe.

    Menus are developing below the page, because they are too long!

    But they remain accessible, for example by scrolling the mouse wheel, or with your finger (on the menu) on a smartphone or tablet.

    I see adds on all videos.

    Use a good free add remover software.

    The site is loading random pages at startup.

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    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).
