Jabiru Aircraft J170

 

j170sp


The J170 was developed with the flying schools in hotter climates in mind. It is the J160 with the longer wings of the J230 and a bigger elevator. The longer wings allow it to climb faster in the hot conditions. The longer wings also provide more float on landing which is helpful when learning to land. The dual controls and adjustable rudder pedals are continued in this model. The 100 knot TAS cruise speed is still easily achievable at 2850 rpm.


The J170 Designed to ASTM 2245 American Light Sport Aircraft Airworthiness Standard. and the Transport Canada Advanced Ultralight Standards. Other versions of the J170 are also available in several countries in Europe. Some are available as factory built arcraft.A high-winged, strut-braced monoplane with wing flaps, mass balanced elevator and in-flight adjustable trim. Cruise Speed @ 2850 rpm 100 knots (True Airspeed) Range (nil reserve) 1030 nautical miles at most efficient speed. 4 stroke JABIRU 2200 cc engine designed specifically for the Jabiru aircraft. All the engine management features of conventional GA light aircraft: Carburettor air heating, dual ignition systems. The engine uses a pressure compensating carburettor with automatic mixture control, giving simple single lever power control. 45 Knot stall speed without flaps at 600kg. Fully enclosed quiet cabin, seats 2 in comfort whether training or cruising. Ergonomically designed cockpit has side-by side seating, centre controls and panel mounted throttle, plus the option of adjustable rudder pedals. Hard-wearing cabin interior includes easily removed seat covers for simple cleaning. 2 large doors provide easy entry & egress. Low cowls and large windows provide excellent visibility. Tricycle undercarriage, steerable nose wheel and hand operated in line hydraulic disc brakes make ground handling simple. Large ailerons and winglets give excellent cross wind handling performance. All composite construction removes the corrosion problem. Wing and power loadings provide high performance and handling. Efficient high aspect ratio wing gives excellent lift combined with low drag. The wide wingspan gives great stability in turbulence and allows comfortable operations at high altitude or from short runways. Designed to need minimal, simple maintenance. Auxiliary electronic fuel pump for ease of starting.


The J170 has the same landing gear and wing as used on Jabiru's 4 place aircraft at a much higher gross weight.


Jabiru aircraft use some common maintenance items sourced from the automotive industry helps keep costs to a minimum. Spark plugs, oil filters, distributor caps, and rotors are all readily available at auto parts stores at auto parts stores at auto parts prices. Oil changes require only 2.5 quarts if Aeroshell 100W.

The Jabiru J170-SP is proudly manufactured in the USA. The design is Australian certified and both the design and manufacturing are in full compliance with the FAA-approved ASTM consensus standards for design, manufacture, quality assurance, and continuing airworthiness. It has been designed to meet the US Sports Plane category and the Transport Canada Advanced Ultralight Standards.

The J170 LSA Kit base price in 2010 was A$35,400.00.

The J170-C had received a handling upgrade in January 2011 which had been well received by customers and we wanted to take the aircraft a step further and early 2013 the J170 model came in for attention to improve its handling and usability. The basic idea was to move the engine forward which has the effect of moving the empty CG of the whole aircraft forward. In a J170 the entire payload (crew, fuel and baggage) all are positioned aft of the CG, so by moving the empty CG forward the aircraft is, in theory, able to carry more payload without running into CG issues.

With the longer engine mount, the engine now had too much leverage on the airframe so that at low speed and high power the aircraft wanted to follow the engine around to the left. The directional stability also suffered a bit as Dutch Roll returned and in some of the more unusual and extreme spin conditions the aircraft didn't recover as it should have. The engine needed a new engine mount, cowlings, exhaust, ram-air ducts and throttle cable. New-shape ailerons worked better at low speed and a new-shape fin and rudder improved the directional stability. They were able to change back to the old (small) ventral fin under the tail - though the aft CG limit of the aircraft did move forwards slightly. A change in the angle of attack of the horizontal tail improved the elevator performance.

The testing on the J170 totalled over 40 flight hours and around 250 individual spins - all carried out by independent test pilot Keith Engelsman. Structural testing also required the application of about 16 different load cases on the fin and horizontal tail. Because of all the changes compared to the earlier J170-C, the finished aircraft is the J170-D. The finished aircraft flies similarly to a J170-C - directional stability is quite good and does not need too much pilot input. Banking turns without using the rudder result in the balance ball coming out of centre by about half a ball - which is about the same as the larger J230. Dutch Roll - which is the tendency of the aircraft to draw a “∞“ shape on the horizon with its nose - is also much improved over the original prototype. Again it's now similar to the J230 which is a pretty "solid" handling aircraft.

The new engine mount uses more engine thrust offset than the previous version which has made the aircraft neutral with different power settings - on take off just a tiny amount of right rudder is required to keep the aircraft straight while on landing (low power) a small amount of left rudder is needed. Similarly the new angle of the horizontal tail makes the aircraft easier to trim.
