The LP1 Is The Best Home Built Aircraft In The World
The LP1 (Light Plane 1) is a home built aircraft kit manufactured by Algie Composite Aircraft and available only through Woodward Aerospace. They do the manufacturing and we handle the customer support and builder assistance.
The LP1 assembles much like a plastic model kitset or a 1:48 scale model that you might find in your local hobby shop. Every part of the LP1 kit interlocks and self- aligns with it's mating part. There is no other aircraft kit that uses this quick build technology. Beginners often think a home built aircraft is either too hard or too time consuming. Woodward Aerospace has a philosophy that neither of those should or will be a factor in the aircraft kits we represent.
For example, all juncture joints of the LP1 are fully filleted. A fillet (pronounced "fill-it") is a concave easing of an interior corner of a part design. Most aircraft have additional parts like fairings that need to be assembled in order to the fillet. There are no fillet cover panels or fairings on this home built aircraft as each part has half of the fillet built in (i.e. horizontal stabilizer to vertical stabilizer, see picture to left).
All fuselage joints such as upper to lower halves join with a knuckle type joint for true alignment rather than a lap. Just adjoin the pieces to align them and glue them together (with really strong epoxy adhesives) and you will have a home built aircraft that is significantly lighter than aluminum and stronger than steel.
The cockpit is a two- piece moulding including the front and rear bulkheads. Just two pieces to the cockpit and you are done! The cockpit has large radiused corners which makes an excellent pressurized cell.
The nose of the aircraft forms a crushable structure in the unlikely event of an impact and with the roll-over protection, the cockpit remains intact.
The elliptical planform wing houses four lightweight fuel bladders rather than a wet type design for improved fire prevention and safety. The wing has no ribs and instead uses nomex honeycomb in it's skins for structural support. The main and secondary spars are an integral part of the skin and bond at the horizontal joint in the middle, as are the horizontal and vertical stabilizer spars. Thus the skin becomes a true sparcap utilizing uni-directional carbon for ultimate strength and light weight. The main and secondary spar carry- throughs in the cockpit are not simple holes cut into the fuselage and glassed over but molded in so the spars and wing fits up from underneath. This also ensures that the cockpit is sealed and stops the fuselage from trying to expand with it's internal pressure.
The cockpit door is also integrally laid up with an internal flange for a blow out seal type to withstand the 10 psi differential pressure on it at FL290. The hydraulically damped main landing gear fastens to the back of the secondary spar inside the fuselage and electrically retracts into the aft of the cabin. The hydraulically damped nose wheel retracts up into the front bulkhead, and is mounted by a lightweight carbon mount under the engine oil pan, which also aids in engine protection in the event of an accidental gear up landing.
The engine is removable while still on the landing gear. Also, access panels and wheel well covers are not just cut-outs but laid up integrally yet still 90% detached separate parts.
First, this is a well engineered design, maybe the first and only home built aircraft to be designed for the home builder. All of the details are built into a complete package that becomes an enjoyable kit to construct. Second, it really performs while still having great low speed characteristics and all at a reasonable price for the immense technology that goes into it!
"….all with their own completion satisfactions, and the joys of being able to intermingle the engineering of each into one complete, well thought out project that will take on a life and legacy of it's own someday."
