WPS TURBINE T62 /150

Introduction
These turbine is specifically designed to be the most concentrated amount of continuous power in as small and light a package. T62/150 is based on the original Solar T62T-32 Titan Gas Turbine Engine (aluminium / magnesium), produce the same power but is NOT same as the large and heavy T62T-32.The fuel control system (FCU) is Mechanical and not Electronic. Because of these major differences, installation and flyability are far greater than a standard T62T-32 conversion and the CG is not grossly effected. It's why T62/150 is specifically designed for home built aircraft use.

Model and type
T62/150. Turboshaft, 1-stage centrifugal compressor annular combustor,1-stage turbine.

Compressor
Radial air intake between compressor and reduction gearbox Single-entry impeller mounted back-to-back with turbine wheel on main shaft supported in ball thrust and roller bearings. air mass flow 2.2 Ib/sec.

Turbine
Radial inflow type. Turbine wheel with integral vanes and exhaust in center. Max exhaust temperature 1,180° F (638°C) at 61,091 rpm.

Exhauts
Fixed area outlet at rear of turbine

Power Outlet
Reduction gearbox at front of unit. Output shaft 6,480 rpm.

Fuel System
1 Adel fuel pump 600 psi fuel control

Ignition
High-energy capacitor discharge ignition. 1 igniter.

Lubrication
Return system. 15-65 psi integral oil tank.

Electrical
12V-14V / 40 A alternator.
12V / 1.0 KW starter.

Power weight
1.25 shp/lb

Couple
121.6 lb/ft at 6480 RPM

Fuel Consumption
Approx 14 to 15 gph (gallon per hour) at cruise setting.
Approx 18 to 21 gph at 100% power.

Oil consumption
0.02 phr

Fuel Spec.
Jet-A and Kerosene are much prefered.
Diesel/gas (85/15) reduces the smoking problem and makes starting in cold climates much easier but is a VERY flammable.
Straight diesel smokes substantially and has a very strong exhaust odor but will be easier to obtain.

Oil Spec
Mil L 23699 or Mil L 7808
Mobil Jet Oil II or Aeroshell 500.
NEVER Exxon 2380, Mobile Jet 254 or Aeroshell 560
Quantity : 3 Quart / 2,8 Litres

Rating max cont.
150 shp / 61,091 rpm / sea level.
168 shp at 43°F/ of 3 min maximum.

Output rotation direction
Viewed looking directly at the output's female 1-1/4 spline socket : Clockwise.

Width and diameter
15 in
10.75 in (at compressor/burner)

Heigth
18 in

Length
30 in with starter.

Maintenance

There is no specific TBO. This is because the main high speed turbine components of these units are factory listed as " On Condition ".

During First 40 hours :
5 Hour interval :
Remove and inspect magnetic plug.
Remove and inspect oil filter for metallic particles. Reuse if not dirty.
10 Hour interval :
Remove alternator and squirt 2cc of engine oil into square drive in alternator gear. This is to lubricate the starter drive.
Remove and check fuel filter in fuel pump. You should be able to blow through the filter. This filter is metallic and may be cleaned in an ultrasonic cleaner.

After first 40 hours :
25 hour interval :
Remove and inspect magnetic plug for metallic particles.
Remove and inspect oil filter for metallic particles. Reuse if not dirty.
Remove alternator and squirt 2cc of engine oil into square drive in alternator gear.This is to lubricate the starter drive.
Remove and check fuel filter in fuel pump. You should be able to blow through the filter.This filter is metallic and may be cleaned in an ultrasonic cleaner.

Annualy :
Perform 25 hour inspections above.
Drain oil, check for clarity. If oil remains a clear amber color, it is ok to reuse. Oil should be changed every 100 hours or 2 years.

Hot Section :
Remove combustor.
Inspect interior for excessive soot and carbon.
Clean if necessary. Remove 6 turbine nozzle retaining screws and remove nozzle from turbine.
Inspect nozzle vanes and turbine blades for burning or rubbing. If ok,re-install and safety wire retaining screws.
Reinstall combustor.
