Deskpilot Posted May 20, 2012 Posted May 20, 2012 Can anyone help me with the translation of the following text. I've tried on-line programs and they seem to think it's Romanian but it can't be translated very well at all. It's text that accompanied a photo of Andre Stark's AS-37. I have tried French but that's a no go as well.

FlyingVizsla Posted May 20, 2012 Posted May 20, 2012 Like any language with a grammatical structure different from ours, it takes some creative work to arrive at a translation. Using several web translators and a Romanian dictionary, some aviation knowledge and paraphrasing like mad - the first part reads: The inset small picture in Fig 7 shows the plane AS-37, an amateur building project of Andre Starck with unique features, intended to have a top speed of 180km/hr, a minimum (stall?) of 70km/hour and a flight distance of 1500km. Here's the issue with languages: Postul de pilotaj este dublu, cu dispunere transversal a celor doua scaune ale pilotilor. The computer translates it as Pilotage station is double, with transverse arrangement of the two positions of pilots. I paraphrase it as Two seat, dual controls - but 'transverse' could refer to the seating positions (tandem, side by side?) rather than the controls can be crossed over to either pilot. Sue
FlyingVizsla Posted May 22, 2012 Posted May 22, 2012 The following is my feeble attempt at a translation (thanks to a dictionary or two, and several web translators). Could do more, but I am working away for 10 days. The small inset picture in Figure 7 shows the plane AS-37, Andre Starck’s amateur building project with unique features, intended to have a top speed of 180km/hour, minimum of 70km/hour and a flight distance of 1500km. The originality of this small bi-plane consists, first of all, in the fact that the two wings are much (some letters missing..) offset from each other, (some letters missing ana) faja (root of ‘face’ ‘surface’) and two propellers are inserted between the wings evenly (in plan view). Through such an arrangement is an unusual layer objine (root of to obtain, derive, extract ..) limit of intake manifold on the upper wing and a (extradosul – no idea) construction of this layer on the lower wing in this way, the critical incidence angle increases, yet it maintains the capacity to control the device, micsorindu (derivative of to make smaller, micro inputs, ) - accordingly the minimum flying speed and the length of the takeoff-landing (DAS category aircraft). It is lovirit (root is to strike, percussion ) and the danger to the ground by the blades of the propeller and to people passing by. You may notice the aerodynamic surfaces sloping at 45 degrees and extremitatile (root added or external,), which connect the wings and also hold an eleroanele (eleron = aileron). Through such an arrangement reduces losses due to the reduced vortices of their wings (at the end), you get a dihedral effect (without it being necessary for the wings to be arranged in a “V”), increases in the resistance to inconvoiere (?) and torsion of the two wings. In addition, both increases the efficiency of eleroanelor (eleron = aileron, plural?) due to their spacing towards the maximum longitudinal axis (rolling) of the machine, as well as because the steep droop (infundare) their incidence is less than the actual incidence of the wings. In other words, these allow a kind of eleroane (aileron-ish?) coborire (to descend, to droop) (parachute like), without loss of control. This miniavion (light plane, ultralight, small plane) is equipped with a motor car 4-cylinder Citreon G-12 C.P. 60. Fuel consumption is 9 litres per hour or 6 litres/100 travelled in flight. The construction of the timber frame is spruce, covering contrapjacaj (no idea). The wing profile is constant throughout the length of the two wings and rectangular in plan (the 34 ribs are identical). Pilot seating is double, with transverse (cross-ways, side by side) arrangement of the two pilot positions.
Deskpilot Posted May 23, 2012 Author Posted May 23, 2012 Hi sue, many thanks for your persistence and patience. Sorry to say that it doesn't give me much more info than I already knew. In your fist reply, the 'transverse' refers to the controls. the design would probably been even fast if it were tandem seating due to lesser frontal area. Even so, it's top speed of 180km/hr is good for a 60hp engine. For anyone interested, here's an extract from the Knoller-Betz Effect explanation: The Knoller-Betz Effect http://www.citeulike.org/user/chliang/article/7509770 http://adsabs.harvard.edu/abs/1998AIAAJ..36.1240J AIAA Journal, vol. 36, issue 7, pp. 1240-1246 Experimental and Computational Investigation of the Knoller-Betz Effect Jones, K. D.; Dohring, C. M.; Platzer, M. F. Abstract -- The ability of a sinusoid-ally plunging airfoil to produce thrust, known as the Knoller–Betz or Katzmayr effect, is investigated experimentally and numerically.Water-tunnel experiments are performed providing ow? visualisation and laser Doppler velocimetry data of the unsteady wakes formed by the plunging foils. Vortical structures and time-averaged velocity pro les? in the wake are compared with numerical computations from a previously developed inviscid, unsteady panel code that utilises a non-linear wake model. Qualitative and quantitative comparisons are excellent over a broad range of reduced frequencies and Strouhal numbers, indicating that the formation and evolution of the thrust-indicative wake structures are primarily inviscid phenomena. Results at Strouhal numbers greater than about 1.0 (based on plunge amplitude) demonstrate non-symmetric, detected wake patterns, where both an average thrust and an average lift are produced. These highly non-linear wake formations are generated reproducibly, both experimentally and numerically. Now you're as knowledgeable as I am
