1. Purpose: I. Reconnaissance aircraft (land); II. Shipboard reconnaissance aircraft.
2. Designation: Fl 282 B-0 (with no cockpit glazing). Fl 282 B-1 (plexiglass glazed canopy).
3. Crew: one pilot
4. Design: Single-engined helicopter and gyroplane of mixed construction with two rotors.
(a) Fuselage: Welded steel tube, truss-type construction. Forward section with open (B-0) or enclosed (plexiglass] cockpit (B-1). Recess for back-type parachute in rear wall of seat. The fuselage center-section contains the entire power plant, the outer skin consists of removable doors, hoods and panels. Oval cross-section. The rear fuselage is fabric-covered with a rectangular cross-section.
(b) Rotor Blades: A tubular steel spar with riveted-on wooden ribs and plywood skin with fabric covering. Rectangular outline with rounded tips. Attached to rotor head with delta and alpha hinges. Receptacle for balance weight at end of spar (scrap). The axes of both rotors are angled outboard at 12? from the vertical. Seen from above, the right rotor rotates clockwise, the left counterclockwise.
(c) Control Surfaces: No elevator. Two-part horizontal stabilizer with single spar. Tubular steel spar with riveted-on wooden ribs. Plywood leading edge, fabric-covering, cantilever construction. Angle of incidence adjustable between -15 and +5? from cockpit.Rudder: wooden construction, fabric-covered, deflection to 40?. Vertical stabilizer: wooden construction with plywood leading edge and fabric covering, bolted to fuselage frame. No ailerons.
(d) Undercarriage: Braced fixed nosewheel with VDM oil shock-absorber leg, coupled with rudder foot pedals (steerable nosewheel). Nosewheel: EC tire 350 x 150mm. Mainwheels: EC tires 465 x 165mm.
5. Power Plant
(a) Engine Type: 1 BMW 314 E. Output: 160hp, compression ratio 1:6.0, rotor reduction ratio: 1:12.
(b) Transmission: Lower transmission flange-mounted on front of engine, in front cooling fan on extended crankshaft. Upper transmission, linked to the lower by a double cardan shaft. Firewall over and behind the engine.
(c) Fuel Tank: An unprotected metal tank located behind the firewall in the aft fuselage, consumable content 105 liters.
(d) Oil Tank: An unprotected 10-liter metal tank flange-mounted on the lower gearbox. Oil content of upper gearbox = 5l.
(e) Type of Fuel: 87 octane aviation gasoline.
(f) Cooling System: Continuous cooling provided by an eight-blade wooden cooling fan with direct drive from the engine. Oil cooler which is switched off for cold-weather operalion.
(g) Control System: Control about all three axes by means of periodic or constant changes in angle of incidence of the rotor blades by means of stick and rudder pedals, to which the rudder is connected. Change-over from helicopter to autogiro (autorotation) flight and reverse achieved by means of a speed-sensitive hydraulic regulator controlled by a hand-operated control lever; change-over to autorotation mode is automatic in the event of engine failure.
(a) Flight Instruments and Navigation Equipment: 1 airspeed indicator, 1 altimeter, 1 vertical speed indicator, 1 turn-and-bank indicator, 1 RPM indicator for rotors, 1 rotor blade angle indicator, 1 master compass, 1 dash-board clock.
(b) Safety and Rescue Equipment: 1 back-type parachute, 1 first-aid kit, 1 one-man inflatable raft (shipboard reconnaissance version).
(c) Radio and Signalling Equipment: 1 FuG 19 radio installation, 1 rigidly-mounted single-barrel flare pistol, 1 rigidly-mounted signal lamp (shipboard reconnaissance version).
(d) Bomb-Release Mechanism: 1 bomb magazine for two 5kg explosive devices (ship board reconnaissance version). 1 magazine for smoke buoys (shipboard reconnaissance version).
8. Special Equipment: Deck-landing equipment, consisting of: 1 tether with landing cable and electrical release.
9. Dimensions: Length of aircraft: 6150mm. Width, including undercarriage and tail surfaces: 2400mm. Height with rotor blades removed: 2400mm. Rotor diameter: 12000mm.
10. Technical Data: (a) construction group: H 3; (b) maximum allowable flying weight: 1.000kg; (c) wing loading: 8.84 kg/m2 (based on rotor surface area); (d) maximum allowable speeds: as helicopter: forward: 80 km/h, backward: 30km/h, sideways: 20km/h; as autogiro: 60km/h; (e) minimum allowable speeds: as helicopter: no limitations; as autogiro: 40km/h, aerobatic forbidden!
11. Performance: (a) Speed: Speed is temporarily limited to 80km/h in horizontal flight in helicopter mode for reasons of structural strength, 60km/h in autogiro mode.
(b) Rate of climb: 4.5m/s at sea level, 3.5m/s at 1000m, 3.0m/s at 1500m. Maximum altitude temporarily restricted to 1500 meters for flight safety reasons.
(c) Takeoff and Landing Performance: Takeoff and landing are made vertically. Autorotation landing in event of engine failure. Landing distance from height of 20m: 50m, stopping distance 15m (with wind speed of 5m/s).
12. Range: Endurance of 2 hours 5 minutes at maximum allowable
